Jamie and Raul both work at the Pizza House. Together, they work a total of 15 hours per week. Raul works 3 more than twice the hours as Jamie. How many hours does Jamie work per week? Enter your answer in the box.

Step-by-step explanation:

List the facts phrase by phrase.

Total = 15 hours

Let Raul's hours = x

Let Jamie's hours = y

Total = x + y = 15

x = 3 + 2y

From total, find x

x+ y = 15                    Subtract y from both sides.

x = 15 + y                   Put the value for x in x = 4 + 2y

3 + 2y = 15 + y           Subtract 3 from both sides

2y = 15 - 3 +y            Combine

2y = 12 + y                 Subtract y from both sides.

2y - y = 12                  Combine

y = 12

Jamie worked 12 hours

Raul worked 3
