Answer:
1. 10x + 9
2. 14x + y
3. 9g + 32
4. 5b + 15
5. 6x + y
Explanation:
"Like terms" are terms that have the same variable and are raised to the same power. We can simplify these expressions by combining the like terms.
Example #1
12x + x - 3x + 7 + 2
(12x, x, and -3x are like terms. 7 and 2 are like terms.)
12x + x - 3x + 7 +2 = 10x + 9
