Equation 2: -8x = 8-20y
Step 1: Cancel out the Ys
-6x = 26 - 20y --> -6x = 26 - 20y
(-8x = 8-20y) x -1 --> + 8x = -8 + 20y
2x = 18
x = 9
Step 2: Plug in X and solve for Y (P.S. you can plus X into either of the equations)
-6(9) = 26 -20y
-54 = 56 - 20y
-80 = -20y
y = 4
Step 3: Check the
-6(9) = 26 - 20(4)
-54 = -54
Therefore:
x = 9 y = 4
