We can multiply Leroy's hourly wage by the total number of hours he worked. On Friday, Leroy spent a total of (3 1/2 + 2 1/2) hours = 6 hours working. If he earns $11.75 in 1 hour, multiplying this by 6 gives $70.50, so this is the total amount he earned on Friday.

Answer: n = -2

Step-by-step explanation:

3n +2(n + 2) = 9n + 12

(simplify 2(n + 2)) =

3n + 2n + 4 = 9n + 12

(subtract 9n from both sides)

3n + 2n - 9n + 4 = 12

-4n + 4 = 12

(subtract 4 from both sides)

-4n = 8

(divide -4 from both sides)

n = -2
