If you would like to solve the system of equations 2x + y = -4 and y = 3x + 2, you can do this using the following steps:
2x + y = -4
y = 3x + 2
_________
2x + y = -4
2x + 3x + 2 = -4
5x = -4 - 2
5x = -6
x = -6/5
y = 3x + 2 = 3 * (-6/5) + 2 = -18/5 + 10/5 = -8/5
(x, y) = (-6/5, -8/5)
The correct result would be (-6/5, -8/5).
