William is 3 years older than Charmaine. The sum of 3 times Charmaine's age and 2 times William's age is 76. How old are William
Aleksandr [31]

w is william, c is charmaine

w = c + 3

3c + 2w = 76

substitute c + 3 for w

3c +2(c + 3) =76

3c + 2c + 6 = 76, combine the c's and subtract 6 from both sides

5c = 70

c = 14

w = c + 3

so w = 14 + 3

w = 17
