$x = 128$ $x=128$

Set up a proportion with $- 32$ $-32$ over $1$ $1$ , because any whole number over $1$ $1$ is the number

$- \frac{x}{4} = - \frac{32}{1}$ $-x/4=-32/1$

Because it is a proportion, cross multiply

$- x \times 1 = - x$ $-x xx1=-x$

$4 \times - 32 = - 128$ $4xx-32=-128$

$- x = - 128$ $-x=-128$

Isolate $x$ $x$ by dividing by $- 1$ $-1$

$x = 128$ $x=128$
