Let M = Mary's age
Let B = her brother's age
.
Here's what we're told in the question:
16 = 4B
Divide each side by 4
4 = B (brother's age)
.
The question is asking what M will be when M=2B.
Since B is 4, M is 4*2 or 8.
.
Odd question because it reads "how old WILL Mary be..." That time has already passed.
