y, Lee
x, Mother
system%28x=3y%2B2%2Cx%2By=54%29

highlight_green%283y%2B2%2By=54%29------------Lee is 13.


highlight_green%28x=3%2854-x%29%2B2%29---------Lee's MOTHER is 41.
x=162-3x%2B2
4x=164
x=41

Lee's mother is two more than three times Lee's age. The sum of their ages is 54. Write a linear equation to determine their ages.
Let Lee's age be L

The mother's is 54 - L

We then get: highlight_green%28matrix%281%2C3%2C+54+-+L%2C+%22=%22%2C+3L+%2B+2%29%29

It's obvious that when the above is solved, Lee's age will be known.

From there, his mother's can be too!
