Unfortunately, solution #4 is not the equation in question #4. (numbers are correct but the signs are different) 4x(2) -2x +5 2x | 8x(3) | -4x(2) | -5x -x | -12x(2) | +6x | +15 -12x(2) - 4x(2)=-16x(2) +6x - 5x = x 8x(3) - 16x(2) + x + 15 Is my solution

4x(2) -2x +5
2x | 8x(3) | -4x(2) | -5x
-x | -12x(2) | +6x | +15
-12x(2) - 4x(2)=-16x(2)
+6x - 5x = x
8x(3) - 16x(2) + x + 15
Is my solution
