Question

Add: (8x + 2y – 3z – 4) + (–4x – 5y + 4z + 6)

A. –4x + 3y – z + 2
B. 4x – 3y – z + 2
C. –4x + 3y –z – 2
D. 4x – 3y + z + 2

Answer 1

First we simplify this problem to:
8x + 2y + -3z + -4 + -4x + -5y + 4z + 6

Answer 2

Now, we combine like terms:
(8x + -4x)+(2y + -5y)+(-3z + 4z)+(-4 + 6)
