Let L = Leah's age
S= Sue's age
J= John's age
L = S+6
J= L + 5 = (S+6) + 5 = S + 11
L + S + J = 41 Substitute everything to obtain an equation in S alone:
(S+6) + S + (S+ 11) = 41
3S + 17 = 41
Subtract 17 from each side:
3S + 17 = 41 - 17
3S = 24
S= 8 Sue
L= 8+6 = 14 Leah
J= 6+11 = 17 John
Check: 8 + 14 + 17 = 41
