Question

Only simplify, don’t solve please. thank you!

Answer 1

Answer:

4x

Step-by-step explanation:

the -8 and +8 cancel out

x and 3x are both positive so add them

you're left with 4x

Answer 2

Simplifying is the same as solving this question. I'll give steps instead.

x - 8 + 3x + 8

x + 3x - 8 + 8       (Arrange the equation)

(x + 3x) (- 8 + 8)   (Parentheses the like terms together)

(4x) (0)                 (Solve)

4x                        (Simplified)
