I would really appriciate it if you would assit me in this Thanks. Answer by Earlsdon(6294) (Show Source):
You can put this solution on YOUR website! Peter's age = x.
His sister's age = x+5
Subtract 84 from both sides. Solve for x by factoring. Discard, as ages can't be negative. Peter's age is 7 years old and his sister is 12 years old.
