User: Solve the linear equation. -2x - 2 + 7(x + 1) = 2x - 4

Weegy: -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; x = -3

6x - 7 + 3(x + 1) = 4x - 6;
6x - 7 + 3x + 3 = 4x - 6;
9x - 4 = 4x - 6;
9x - 4x = -6 + 4;
5x = -2;
x = -2/5

-4 is the answer for x + 1 over 6 and x + 2 over 4.
(x+1)/6=(x+2)/4
(x+1)/3=(x+2)/2
2*(x+1)/3=x+2
2x+2=3(x+2)
2x+2=3x+6
3x-2x=2-6
x=-4.
