<em></em>
Step-by-step explanation:
Given
Represent their ages with the first letters of their names:



Required
Determine their individual ages
We'll solve the above equations using substitution method of simultaneous equations
Substitute 15 + S for T and 4 * S for R in 
This gives:


Collect Like Terms


Divide through by 6


<em>This implies that Sandy is 12 years old</em>
Substitute 12 for S in
and 




<em>This implies that Randy is 48 years old and Todd is 27</em>
