$x=-6$

We need to get the x alone. Thus, we cancel out the addition by subtracting 3 on both sides. This leaves us with the equation $-x/2=3$. In order to cancel out division, we use multiplication, so we multiply both sides by -2 to get that $ x=-6$. We plug -6 in for x and confirm that our answer is, indeed, correct.
