Instead of doing your problem for you, I'll do one exactly like it with
different numbers. Below is the problem I will do for you. Use it as a
model to solve yours by. It's done step-by-step just like yours,
James is ¼ the age of his father, Steve. The two have a combined age of 75.
How old is James? How old is Steve?
James is ¼ the age of his father, Steve.
| | | |
J = ⅓ S
Getting it together
J = ¼S
The two, James and Steve, have a combined age of 75.
| | | | |
J + S = 75
Getting it together
J + S = 75
So we have:
Substitute ¼S for J in
J + S = 68
Multiply through by 4
J = ¼S = ¼(60) = 15
How old is James? 15
How old is Steve? 60
Now do yours the exact same way.
