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 and charmaine?

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
