Answer:
4x - 2
Step-by-step explanation:
(5x - 10) + (-x + 8)
To solve this problem, one must simplify, combine like terms. One can only combine a variable unit with another variable unit, likewise, one can only combine a constant (numerical term) with another constant.
(5x - 10) + (-x + 8)
= 5x - 10 - x + 8
= 4x - 2
