Question
Solve $\frac{3 x}{4}+5=\frac{1}{2}$

Answer

We have, $\frac{3}{4} x+5=\frac{1}{2}$
$\Rightarrow \quad \frac{3}{4} x=\frac{1}{2}-5=\frac{1-10}{2} \Rightarrow \frac{3}{4} x=\frac{-9}{2}$
$\Rightarrow \quad x=\frac{-9}{2} \times \frac{4}{3}$ [multiplying both sides by $\frac{4}{3}$ ]
$\Rightarrow \quad x=-6$
