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.

a.
x + y = 425
y = 2x – 40

b.x + y = 425
y = 2x + 40

c.
x – y = 425
y = 2x – 40

d. x + y = 40
y = 2x – 425

425 was the total. This means that 425 has to get one side of the equal sign, meaning it can't be D.

"Anita's was 40 less than twice Joelle's"  

this means 2x-40

A would be it since their COMBINED scores are 425, and that gives us the answer.
