Let Sam's age now be S
Let her Mother's age now be M
6 years ago Mrs. Smith was 5 times as old as her daughter Sam
M-6 = 5(S-6)
How old is Sam now if her age is one third of her mother's present age?
Since Sam's age now is one third of her mother's present age,
S =
M
Multiply that through by 3 to clear the fraction:
3S = M
Substitute 3S for M in
3S-6 = 5(S-6)
Solve that for S.
