Answer:
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
x=-8z/5 - 3y/5
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.
