User: -2x - 2 + 7(x + 1) = 2x - 4

Weegy: I assume you want to solve for x, in which case you have to make this into an equation. If this was actually 2x + x -3 = 0, then x=1

-2x - 2 + 7(x + 1) = 2x - 4
-2x - 2 + 7x + 7 = 2x - 4
5x + 5 = 2x - 4
5x - 2x = -4 - 5
3x = -9
x = -9/3 = -3

5[-2x - 3 - 4(x + 1)] = 7x - 4
5(-2x - 3 - 4x - 4) = 7x - 4
5(-6x - 7) = 7x - 4
-30x - 35 = 7x - 4
-30x - 7x = - 4 + 35
-37x = 31
x = -31/37

14x - 2y = 12 (eq.1)
6x + 4y = 44 divided by 2 on both sides:
3x + 2y = 22 (eq. 2)
adding up eq. 1 and 2 the result is:
17x = 34
x = 2
14(2) - 2y = 12
-2y = 12 - 28 = -16
y = 8
The solution for system 14x - 2y = 12 6x + 4y = 44 is (2, 8)
