    x=-8z/5 - 3y/5

    Step-by-step explanation:

    distributive prop

    3x-3y=8x+8z

    isolate x by moving 8x to the left, and - 3y to the right

    -5x=3y+8z

    divide by - 5 on both sides.

    x=-8z/5 - 3y/5

    Step-by-step explanation:

    3 (x - y) = 8 (x + z)

    3x - 3y = 8x + 8z

    -3y - 8z = 8x - 3x

    -3y - 8z = 5x

    (-3y - 8z) / 5 = x ... or could also be written like : x = - 3/5y - 8/5z
