Anita and Joelle bowl together and their combined total score for one game was 425 points. Anita’s score was 40 less than twice Joelle’s. What were their scores? Write a system of equations to model the problem if x represents Joelle’s score, and y represents Anita’s score.
(Points : 1)
x + y = 425
y = 2x – 40

x + y = 425
y = 2x + 40

x – y = 425
y = 2x – 40

x + y = 40
y = 2x – 425

(Points : 1)
       x + y = 425
             y = 2x – 40

       x + y = 425
            y = 2x + 40

       x – y = 425
            y = 2x – 40

       x + y = 40
            y = 2x – 425

The reason is, because the combined scores make 425, it's x+y=425

The second part is because 40 less that 2 times means 2 times-40, and that can be written:

y=2x-40


So, the answer is A.

Joelle's Score: 155
Anita's Score: 270

155*2=310
310-40=270

270+155=425
