x = -5

Step-by-step explanation:

3x + 7 = -8

> subtract 7 on both sides

3x = -15

> divide 3 both sides

x = -5

Answer:

x=-5

Step-by-step explanation:

subtract 7 from both sides

3x = -8 - 7

simplify -8 - 7 to -15

3x = -15

divide both sides by 3

x = -15 / 3

simplify 15 / 3 to 5: and you get.

x=-5
