Question 1166635
<pre>
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,
</pre>
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?<pre>

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:

{{{system(J=expr(1/4)S, J+S=75)}}}    

Substitute ¼S for J in

     J + S = 68

{{{expr(1/4)S + S =75}}}

Multiply through by 4

{{{S+4S=300}}}

{{{5S=300}}}

{{{S=60}}}

J = ¼S = ¼(60) = 15

How old is James?  15

How old is Steve?  60

Now do yours the exact same way.
