$x = - \frac{1}{21}$ $x = -1/21$

Explanation:

You first need to put the x at the top of the fraction, then do the appropriate multiplications to isolate x.

$\frac{4}{7 x} = - 12 \Leftrightarrow \frac{7 x}{4} = - \frac{1}{12} \Leftrightarrow 7 x = - \frac{1}{3} \Leftrightarrow x = - \frac{1}{21}$ $4/(7x) = -12 iff (7x)/4 = -1/12 iff 7x = -1/3 iff x = -1/21$
