I’m not sure I understand what’s going on here. But if you’re saying x=1, and the problem is 4x=?. Then 4(1)=4
So basically, the player made 24 out of 40 free throws, which means that she had gotten 60% of her shots so far. I'm assuming that this means that she has a 60% chance of getting it in next time.
5. y = x + 7
6. y = -x + 1
