Hey there! :)
We're trying to get "x" onto its own side of the equal sign, so let's start out by adding 5 to both sides of the equal sign.
x/4 -5 + 5 = -8 + 5
Simplify.
x/4 = -3
Now, we need to get rid of "4" as the denominator (the bottom number in a fraction). So to do so, we must multiply both sides by 4.
x/4 · 4 = -3 · 4
Simplify.
x = -12
So, our answer is your second answer choice : -12
~hope I helped!~
