#14#

Here's how I did it:

Explanation:

PEMDAS is used in solving math problems that require the use of different operations. The order goes:
Parentheses/Brackets
Exponents
Multiplication & Division
Addition & Subtraction

#3 * 1(5-1) + 8/4(1)#

We need to take care of the parentheses first:
#3 * 1(4) + 8/4(1)#

#3 * 4 + 8/4#

There are no exponents in this expression, so let's do multiplication and division:
#12 + 8/4#

#12 + 2#

And finally we do addition and subtraction:
#14#
