Question 750847
r for Ross age, and h for Holly age.

{{{r=5+2*h}}}, Ross is five years older than twice his sister Holly's age.

{{{r-h=14}}}, The difference in their ages is 14 years. 


I would take r from the first equation and substitute into the second equation, and solve for h.  You could then use what you found for h to find value of r.


{{{(r)-h=14}}}
{{{(5+2h)-h=14}}}
