Question

Evaluate (x - 3y + 4z) + (y - 2x - 8z) + (5x - 2y - 32)​

Answer 1

Required sum,

=(x−3y+4z)+(y−2x−8z)+(5x−2y−3z)

Collecting like terms,

−x−2x+5x−3y+y−2y+4z−8z−3z

Adding like terms,

=(1−2+5)x+(−3+1−2)y+(4−8−3)z

=4x−4y−7z

Answer 2

Step-by-step explanation:

x-2x+5x-3y+y-2y+4z-8z-32

4x-4y-4z-32

4(x-y-z-8)
