Question

Simplify 1 - 3s - s + 8 - 2

Answer 1

Explanation:

first you group like terms.

-3s-s+8+1-2

-4s+7

Answer 2

-4s + 7

Explanation:

We need to combine like terms. Like terms are terms whose variables (and exponents) are the same (note that they could be constants as well). Basically, they are "like" each other. In this case, the like terms are -3s and - s and also 1, 8, and -2. -3s - s = -4s and 1 + 8 - 2 = 7 so the answer is -4s + 7.
