Linear equations are made up of both constants and variables. A linear equation with two variables x and y is an equation of the form Ax + By + C = 0, where A, B, and C are real values.
A pair of linear equations in two variables is two linear equations in the same two variables. Linear equations with two variables are written in standard form:
a1x + b1y + c1 = 0, a2x + b2y + c2 = 0
where, a1, a2, b1, b2, c1, c2 are real numbers, such that a12 + b12 = 0, a22 + b22 = 0.
The necessary answer is the coordinates of the point (x, y) that satisfy the system of two linear equations in two variables. This is the point at which the two lines representing the two equations cross. There are two approaches to solving a pair of linear equations in two variables:
4. Graphical Method Of Solution Of A Pair Of Linear Equations
While solving for the above 2 linear equations, one of the three cases might arise:
To solve the above equations, use one of the three Algebraic approaches listed below:
Step 1 - From one equation, get the value of one variable, say y in terms of x or x in terms of y.
Step 2 – Substitute this number into the second equation to obtain the equation in one variable and the solution.
Step 3 – Now, substitute the value/solution acquired in step 2 into the equation obtained in step 1.
Step 1 – If the coefficients of any one variable in both equations are not the same, multiply both equations by suitable non-zero constants to make the coefficients of any one variable numerically equal.
Step 2 – Add or subtract the acquired equations to generate an equation in one variable and solve it.
Step 3 – Substitute the value of the variable obtained in step 2 into either of the original equations to obtain the value of the other variable.
We write the equations in the following way:
