#### Answer

$x=-24$

#### Work Step by Step

We need to get the x alone. Thus, we cancel out the addition by subtracting 6 on both sides. This leaves us with the equation $-18=3/4x$. x is being multiplied by 3/4, a fraction, so we multiply by the reciprocal, 4/3, on both sides of the equation to obtain that $x=-24$. We plug -24 in for x and confirm that our answer is, indeed, correct.
