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)
Cheers!
Answer:
4x
Explanation:
the -8 and +8 cancel out
x and 3x are both positive so add them
you're left with 4x
