A Linear equation is an equation for a straight line containing variables and constants in the form given below:. If the value of any coefficient or variable is zero then the term containing that coefficient or variable becomes zero.
This is because anything multiplied to zero is equal to zero. A linear equation is a simple equation containing coefficients, constants and one or more variables, but a linear equation can never have exponents and roots. One variable linear equation: A linear equation which has only one variable unknown term represented by alphabets or symbols is known as one variable linear equation.
The coefficient can never be zero. Two variable linear equation: A linear equation is an equation which has two variables unknown terms represented by alphabets or symbols known as a two-variable linear equation. If any coefficient becomes zero then the two-variable linear equation changes to one variable linear equation.
Three or more variable linear equations: A linear equation containing more than two variables is called a linear equation of three or more variables. It can be represented as:.
Till now in the journey of algebraic equations, we have learned solving single equations with only one variable unknown. We solve it differently. So before looking into the solution of a linear equation with two variables let us understand the Linear equation with two variables mathematically. But two equations having two variables each can be solved to find the value of x and y simultaneously.
A group of two or more equations is called a system of equations. Each equation represents a straight line. If two lines are taken then there are high chances that those two lines intersect at a unique point which satisfies both the equations. In order to find the intersecting point, pick two random lines and solve.
We know that every linear equation in one variable has a unique solution. What about the solution of a linear equation with two variables? There will always be a pair of values one for x and the other for y which satisfy the given equation.
Also, note that there is no end to different solutions of a linear equation in two variables. That is, a linear equation in two variables has infinitely many solutions. There are many ways to solve a system of linear equations with two variables. Given below are the two basic methods to solve a linear equation with two variables.
Graphical Method of Solving Linear Equation. Instead of finding the solution of two the linear equations separately we find the solution of the system instead.
If we graph both the lines in the same coordinate system then the point of intersection of two lines will be the solution of the system. For Example: To solve the system of equations having two equations -. The points are to be plotted on a graph. The point of intersection of these two lines will be the solution of the system. Substitution Method of Solving Linear Equation.
The other way of solving a system of linear equations is by substitution method. This system shows how to solve linear equations easily by finding the value of one variable in terms of another variable by using one equation and then replacing this value in another equation. Let's find the solution of the same system of linear equations. Substituting the value of y in equation 1. Thus, we can find the actual value of y by substituting the value of x as -3 in equation 1.
Therefore, the solution of the system of linear equations is -3, Every exam has a pattern to test students' knowledge and their ability to perform in the near future. Practising Class 9 Maths Chapter 4 Solutions increases your speed during exams because a lot of students fail to complete the paper on time.
Practising drills in you the tendency to think of the solution of the given question at breakneck speed.
Also, you can predict the topics that can come in the exam by gauging the frequency and interval of the repeated questions. This can help you strategize your preparation and score good Ch 1 Maths Class 10 Mcq Questions List marks. With practice, you can also solve the unrepeated or brand new questions too because the concept of questions in the question papers usually remains the same.
You also get used to the level or standard of board exam questions. So understand and know the concept while solving questions and you will end up scoring above 90 per cent. It is a well known fact that some of us prepare to score maximum but end up getting less because of our carelessness or conceptual mistakes.
And this can be corrected by a proper practice. Practicing maths problems not just enhances your problem-solving skills but also amplifies your analytical and reasoning abilities which is much needed in today's generation. It is important for all of us to understand and identify problems, think logically, interpret, make decisions and solve the problem.
Test your problem-solving skills. Get used to the structured and standard questions. Check your Chapter-wise knowledge. Increase your confidence level. Gain your Speed. Make it serves as your revision note as well. Download Free Study Material for Class 9 to score more marks.
