Question 1168878

The sum of the ages of two sisters, Mary and Jane, is 24 years. Four years ago three times Mary’s age was 3 years more than twice Jane’s age. Determine their current ages.
<pre>Don't believe what he tells you! Mary's age is NOT a MIXED number, so {{{cross(m=13&3/4)}}}.
In fact, {{{highlight_green(matrix(2,4, Jane, is, 13, years-old, Mary, is, 11, years-old))}}}
You can do the CHECK!!
