-12

Explanation:

When you are looking at equations like this, with one variable and numbers, you always want to start by moving the like terms to one side. In this case:

$- \frac{1}{4} x - x = 3 + 12$ $-1/4x-x=3+12$

And then combine like terms:

$- \frac{5}{4} x = 15$ $-5/4x=15$

Solve for x:

$x = 15 \times (- \frac{4}{5})$ $x=15xx(-4/5)$
$x = 3 \times (- 4)$ $x=3xx(-4)$
$x = - 12$ $x=-12$
