Question 1174978

Melissa's age is two times Steven's age. If Melissa is 12 years older than Steven, what are their ages? 
<pre>Difference in ages: 12 years
The above means that when the YOUNGER reaches the OLDER's age (in this case, 12), the OLDER will be TWICE the YOUNGER's age (2 * 12 = 24, in this case).
So, {{{highlight_green(system(matrix(1,2, 12, years-old), and, matrix(1,2, 24, years-old)))}}}
