Question

Algebra Urgent:
The sum of the ages of Alex and Harry together is 36. If Alex's current age is 3 times as much as Harry's age was 8 years ago, how old is each?

Answer 1

A+H=36
A=3(H-8)

Answer 2

let harry age = x
then alex age is 3(x-8)
therefore
a+x=36
a=3(x-8)

Answer 3

Thanks you both, but the thing is i know that part, i need help on how to get the solution like Alex's and Harry's age each.

Answer 4

substitute the second equation into the firs equation

{3(H-8)}+H=36

now you can solve for h ,

Answer 5

Oh, thanks!!!

Answer 6

{3(H-8)}+H=36
3H-24+H=36
4H=36+24
4H=60
H=15

now plug H=15 into the first equation to solve for A

Answer 7

Yeah i got it :) Thank you so much xD

Answer 8

how old did you determine alex to be/

Answer 9

21

Answer 10

so 15+21=36 it works :)

Answer 11

A=3(H-8)
21=3(15-8)=3x7
too
you have found the correct solution
