William is 3 years older than charmine the sum of 3 times charmines age and 2 times williams age is 76 how old are william and c
harmine
1 answer:
William is 17 and Charmine is 14
let Charmine's age be x then William is x + 3, then
3x + 2(x + 3 ) = 76
3x + 2x + 6 = 76
5x + 6 = 76 ( subtract 6 from both sides )
5x = 70 ( divide both sides by 5 )
x = 14
Charmine is 14 and William is 14 + 3 = 17
