mrs. johnson is 3 times as old as her son. ten years agoe she was 5 times as old as her son was then.
what is the two equations for this problem?
let x = son's age
and y = Mrs. Johnson's age.
============================
y=3x is one equation.
10 years ago Mrs. Johnson' age was y10 and the son's age was x10. At that time, Mrs. Johnson was 5 times older; therefore,
y10=5*(x10) is the second equation. Post your work if you need further assistance.

x=1
y=23
