Question

Given the system of equations: 2x – y = –2 x = 14 2y

Answer 1

If you would like to solve the system of equations, you can do this using the following steps:

2x - y = -2
x = 14 + 2y
__________
2x - y = -2
2 * (14 + 2y) - y = -2
28 + 4y - y = -2
28 + 3y = -2
3y = -2 - 28
3y = -30    /3
y = -30/3
y = -10

x = 14 + 2y = 14 + 2 * (-10) = 14 - 20 = -6

(x, y) = (-6, -10)

The correct result would be (-6, -10).
