5x + 2(x - 3) = -2(x - 1);

5x + 2x - 6 = -2x + 2;

7x - 6 = -2x + 2;

7x + 2x = 2 + 6;

9x = 8;

x = 8/9

8(x + 1) - 3(x + 4) = 7(2 - x);

8x + 8 - 3x - 12 = 14 - 7x;

5x - 4 = 14 - 7x;

5x + 7x = 14 + 4;

12x = 18;

x = 18/12;

x = 3/2

8x + 8 - 3x - 12 = 14 - 7x;

5x - 4 = 14 - 7x;

5x + 7x = 14 + 4;

12x = 18;

x = 18/12;

x = 3/2
