The Elimination Method
Step 1: Multiply each equation by a suitable number so that the two equations have the same leading coefficient. ...
Step 2: Subtract the second equation from the first.
Step 3: Solve this new equation for y.
Step 4: Substitute y = 2 into either Equation 1 or Equation 2 above and solve for x.
Example
Use elimination to solve the system. x – y = −6 x + y = 8
2x = 2 x = 1 Solve for x.
x + y = 8 1 + y = 8 y = 8 – 1 y = 7 Substitute x = 1 into one of the original equations and solve for y.
x – y = −6 1 – 7 = −6 −6 = −6 TRUE Be sure to check your answer in both equations! The answers check.
