folllowing the order of operations (parentheses, exponents, multiplication, division, addition, subtraction or PEMDAS) we know that we need to solve for 8/2 first.
8/2=4
then we know our new equation looks like 20-34+4=x. now we need to add.
34+4=38
now we have the new equation 20-38.
20-38=-18
your answer is -18.
