You can put this solution on YOUR website! Ross is five years older than twice his sister Holly's age.
r = 2h + 5
:
The difference in their ages is 14 years.
r - h = 14
r = (h+14); you can use this form for substitution
You can put this solution on YOUR website! r for Ross age, and h for Holly age.
, Ross is five years older than twice his sister Holly's age.
, 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.
