Question

$z = -8x$, for $x$

a) $x = \frac{z}{8}$
b) $x = -\frac{8}{z}$
c) $x = z + 8$
d) $x = -\frac{z}{8}$

Explanation:

Step1: Isolate $x$ via division

Divide both sides by $-8$.
$$\frac{z}{-8} = \frac{-8x}{-8}$$

Step2: Simplify the equation

Cancel $-8$ on the right side.
$$x = -\frac{z}{8}$$

Answer:

D) $x = -\frac{z}{8}$
