Question 1061388

Laura is four years less than twice her son's age. The sum of their ages is 119. How old is Laura? How old is her son? 
<pre>Let son's age, be S
Then Laura's age is: 2S - 4
We then get the following SUM-OF-AGES equation: S + 2S - 4 = 119
3S = 119 + 4
3S = 123
S, or son is: {{{highlight_green(matrix(1,4, 123/3, or, 41, years-old))}}}
