Evaluate the expression when x = 8 and y = 1.
Rzqust [24]
The answer should be 4.

First, simplify \frac{8}{2} to 4. Your problem should look like: 4 x 1. 
Second, multiply. 4 x 1 = 4 so that is your answer.

Also, 
to start the equation up, make sure to add in the numbers in replace for the letters. Your problem to start with should look like: \frac{8}{2(1)}.
