4. Jimmy tried to solve the system of equations below, but he made an error. |2x−y=18 y = 4x+2 His work is shown. Circle the error he made. Explain the error and show how to solve the system correctly. 2x - 4x + 2 = 18. His mistake was: -2x + 2 = 18 -2x = 16 x = -8 The correct steps are: J= 4(-8) + 2 y=-32 +2 y = -30
