tom is 4 times as old as todd. in 5 years toms age will be 13 years more than 2 times as old as todd. how old is tom?

Question

i really need help figuring out this problem. thank you

Answer 1

Let M=Tom's age, D=Todd's age

M=4D

M+5=13+2(D+5)

substitute

4D+5=13+2D+10

2D=18

D=9

M=36

36+5=13+2(9+5)

41=13+28=41
