Question

Bob is twice as old as ralph. three years ago the sum of their ages was 45. what are their ages now?

answer using a let statement

Answer 1

34 and 17

Explanation:

Bob = B

Ralph = R

B=2R

B-3+R-3=45

B+R-6=45

+6 +6

B+R=51

Substitute B for 2R

2R+R=51

3R=51

R=17

2(17)=34

so B is 34 and R is 17

Answer 2

Were they both 45? I'm kinda confused on that part, but I think Ralph would be 48 and Bob would be 50
