Accepted Solution
A:
Answer: {y,x} = {-6,-2} Step-by-step explanation:/ Solve equation [2] for the variable y [2] y = 2x - 2// Plug this in for variable y in equation [1] [1] (2x-2) - x = -4 [1] x = -2// Solve equation [1] for the variable x [1] x = - 2 // By now we know this much : y = 2x-2 x = -2// Use the x value to solve for y y = 2(-2)-2 = -6
