Today Justin reached 1/11 the age his mother was when he was born.
:
Let x = mother's present age
Let y = Justin's present age
then
(x-y) = Mother's age when J was born
:
y = 1%2F11(x - y)
multiply both sides by 11
11y = x - y
11y + y = x
12y = x
therefore
"Today, Justin's mother is _12_ times as old as Justin.
:
:
Let's see if that will work with real numbers
Let J be 4 yrs old, then Mom is 12*4 which is 48
4 yrs ago Mom was 44 which is 11 times J's present age
