Can possibly be interpreted two ways:
(N - 7)/3 = 5
N-7 = 15 <-- multiplies both sides by 3
N = 15 + 7 = 22 <--- adds 7 to both sides
----------------------------------------------------
N/3 - 7 = 5
N/3 = 12 <--- adds 7 to both sides
N = 36 <--- multiplies both sides by 3
--------------------------------------------------------------------------
If the question were written:
"The quotient of the difference of a number and 7 is five, then
that will be the first case.
