We can set Charmaine's age as x. If William is 3 years older, than his age would be 3 + x. Charmaine = x William = 3 + x Their ages added up together is 76, and we need to multiply Charmaine's age by 3 and William's age by 2. 3x + 2(3+x) = 76 3x + 6 + 2x = 76 5x = 70 x= 14 Charmaine is 14 years old William's age is Charmaine's age plus 3. William is 17 years old.
