Combine like terms

s+2s + 3+12

3s+15

3 (s+5)

Step-by-step explanation:

To simplify the expression, we must combine like terms.

s + (2s+3) + 12

The like terms are the terms with variables (s and 2s) and the terms without variables, or the constants (3 and 12).

To combine the like terms, add them.

(s+2s) + (3+12)

3s+15

This expression can also be factored using the GCF. The GCF of 3s and 15 is 3.

3s+15

Factor out a 3

3 (s+5)
