William is 3 years older than charmaine. the sum of 3 times charmaines age and 2 times williams age is 76. how iold are william and charmaine

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.
