Question 1148975
Maria is 8 years older than her brother, and the sum of their ages is 72 years. 
How old is her brother?
<pre>Let her brother's age be B
Then she's B + 8
We then get: B + B + 8 = 72
2B = 64
B, or brother is: {{{highlight_green(matrix(1,4, 64/2, "=", 32, years-old))}}}
The other person is "DEAD" WRONG!
