x = 25

Step-by-step explanation:

x = # of hrs he worked at his weekday job

w = # of hours he worked at his weekend job

25 + x = 40y = 40 - 25 = 15.

Therefore, Mia worked for 25 hours at his weekday job and 15 hours at his weekend job.

w + x = 40

20x + 18w = 770

18 (x + w = 40) = 18x + 18w = 720

(20x + 18w = 770) - (18x + 18w = 720)

2x=50

x=25
