Elimination Method Steps Step 1 Firstly, multiply both the given equations by some suitable nonzero constants to make the coefficients of any one of the variables (either x or y) numerically equal Step 2 After that, add or subtract one equation from the other in such a way that one variable gets eliminatedNow, if you get an equation in one variable, go to Step 3. Add the two equations together to eliminate y y from the system Divide each term by 5 5 and simplify Tap for more steps x = 4 x = 4 Substitute the value found for x x into one of the original equations, then solve for y y Tap for more steps y = 2 y = 2 The solution to the independent system of equations can be represented as a point.

Answer 2x y = 3 6x 3y = 9 (equation 1) 7x 3y = 4 (equation 2) Adding equations (1) and (2) 13x = 13 x = 1 Substitute x = 1 into (1) 6(1) 3y = 9 6 3y = 9 y = 1 (x, y) = (1, 1). The elimination method for solving systems of linear equations uses the addition property of equality You can add the same value to each side of an equation So if you have a system x – 6 = −6 and x y = 8, you can add x y to the left side of the first equation and add 8 to the right side of the equation And since x y = 8, you are adding the same value to each side of the first.  The solution is ( 3, 1 ) In this case the solution can be found by using the "elimination method" Looking at the two equations I see that you have y in equation one and y in equation two By adding the two equations together I will "eliminate" the y variable and then I can solve for x x y = 2 x y = 4 Add the two equation together and get 2x = 6 x = 3 Now.
