James is six times as old as his granddaughter, Louise. In two years time he will only be five times as old as Louise. How old are James and Louise now?

Answer 1

granddaughter's age---- x
James' age --------- 6x

2 years from now:
granddaughter's age --- x+2
James' age ---------- 6x + 2

6x+2 = 5(x+2)

solve for x
