WebTake the two equations that contain z and solve for z. 3x+5y-4z=36 4z = 3x+5y- 36 z = ¼ [3x+5y- 36] 12x+2y+3z=19 3z = −12x − 2y + 19 z = ⅓ [−12x − 2y + 19] Since we now have to things that are equal to z, we set them equal to each other, eliminating the z. ¼ [3x+5y- 36] = ⅓ [−12x − 2y + 19] WebMay 3, 2011 · Step 2: Subtract ZX from both sides of the equation. Ok, so now I have X - ZX = ZY. I assume that there are a few more steps but I'll be dammed if I can remember. From memory I know I need to remove the Z from the ZX on left hand side of the equation, but can't figure out how. hihi vision app
