The 4x and the -12x can be combined together with the result of -8x
If z = 2
then we can replace z with 2 in the expression:
-8ZX + 4ZY + 20 Z
-8(2)X + 4(2)Y + 20 (2)
-16X + 8Y + 40

Z ( 4X +4Y -12X + 20) =
z ( -8X + 4Y + 20) =
-8ZX + 4ZY + 20 Z

so lets say that the Z is not a Z but a 2 what would the answer be and how would I carry it through? thanks
