You'd want to start this one by setting up an equation.
It's hard to visualize this over this app, but take each math term and assign a matching symbol to it.
For example:
Four (4) more (+) than the quotient (/) of a number (x) and eight (8) is equal = to two (2)
Take the symbols out:
4 + (x/8) = 2
Now, solve algebraically.
4 + (x/8) = 2
x/8 = -2
x = -16
