    the sum of 2x+3y - 6z and 5x-3y = (2x + 3y -6z) + (5x - 3y) = 2x + 5x +3y - 3y -6z = 7x - 6z To get 8x-y+5z from the sum of 2x+3y - 6z and 5x-3y, we need to add something. Let that something be A [ (2x + 3y -6z) + (5x - 3y) ] + A = 8x-y+5z ( 7x - 6z ) + A = 8x - y + 5z Subtract both sides by 7x ( 7x - 6z ) + A - 7x = 8x - y + 5z -7x A - 6z = x - y + 5z Add 6z to both sides A - 6z + 6z = x -y + 5z + 6z A = x - y + 11z So, to get 8x-y+5z from the sum of 2x+3y - 6z and 5x-3y, we need to add x - y + 11z.

    But there are some unknowns there, you can't add them directly because they are NOT the like terms, right?
