Question

solve $5 - kx = 9$ for $x$ assume that $k \
eq 0$. \
\
\\(\bigcirc\\) a) $x = -\frac{14}{k}$ \
\\(\bigcirc\\) b) $x = -\frac{4}{k}$ \
\\(\bigcirc\\) c) $x = \frac{4}{k}$ \
\\(\bigcirc\\) d) $x = \frac{14}{k}$

Explanation:

Step1: Subtract 5 from both sides

$5 - kx - 5 = 9 - 5$
$-kx = 4$

Step2: Divide by $-k$ (k≠0)

$\frac{-kx}{-k} = \frac{4}{-k}$
$x = -\frac{4}{k}$

Answer:

B) $x = -\frac{4}{k}$
