First thing you do is take get everything on the opposite side of x. To do that, start by taking the parenthesis off first. Then take the (-7) and moving it over.

x/-4 + (-7) = (-16)

x/-4 - 7 = -16

x/-4 - 7 + 7 = -16 +7  Remember, whatever you do to one side, you have to do to the other.

x/-4 = -9  Now multiply both sides by -4

x= 36 Remember, the negatives cancel out

Now plug it back into the the original equation to see if it works.
