This year Ben is 4/7 as old as Glen. Fifteen years from now, Ben will be ¾ as old as Glen. At that time, the sum of their ages will be 63. How old are Ben and Glen now?

Answer 1

G = Glen's present age
B = Ben's present age
B = 4/7 G

G + 15 + B + 15 = 63
substitute, B = 4/7 G
G + 15 + 4/7 G + 15 = 63

Solve for G
