8/7/2023 0 Comments Solve using elimination![]() And the equations of coincident lines have infinitely many solutions as they lie on each other so every point is the intersection or the common point of those lines. Equations of two intersecting lines will have only two solutions that are consistent, but the equations of two parallel lines have no solutions as these lines never intersect each other. Step 3: Substitute the value of y in equation 1, we get, x + 12/5 = 8īut what if while multiplying a non-zero constant, we get the coefficients of both the variables equal? What if both the terms got eliminated while adding or subtracting? We get such cases while solving equations of parallel and coincident lines. Step 2: Subtract equation 2 from 1, we get, y=12/5. So, the two equations we have now are 2x + 2y = 16 → (1) and 2x - 3y = 4 → (2). Step 1: To make the coefficients of x equal, multiply equation (1) by 2 and equation (2) by 1. Let us take an example of two linear equations x+y=8 and 2x-3y=4 to understand it better. These are the elimination method steps to solve simultaneous linear equations. Step-4: At last, substitute this value in any of the given equations to find the value of the other given variable.Step-3: Simplify the result to get a final answer of the left out variable (let's say, y) such that we will only get an answer in the form of y=c, where c is any constant.Step-2: Add or subtract both the equations such that the same terms will get eliminated.Step-1: The first step is to multiply or divide both the linear equations with a non-zero number to get a common coefficient of any one of the variables in both equations.Let us look at the steps to solve a system of equations using the elimination method. But it can only be applied to two equations at a time. We can solve three equations as well using this method. ![]() The elimination method is useful to solve linear equations containing two or three variables.
