Question

IM PUTTING THIS FOR 30 POINTS PLEASE ANSWER

Jack's bowling score was 20 less than twice Jill's score. The sum of their scores was 205. Find the two

scores

Answer 1

Jacks scores 130 points

Jill scores 75 points

Explanation:

J=Jacks score

K=Jills score

2K-20+K=205

So, we can do 3K-20=205

+20 +20

(cancel it out)

and we are left with 3K=225 which is K=75, so we do do 205-75=130(which is jacks score). To prove this we can do 75x2=150-20=130
