Answer

$\{-16\}$

Work Step by Step

Multiply both sides by $4$. $4\left(\frac{1}{2}x-4\right)=4\left(\frac{3}{4}x\right)$ Use distributive property. $4\cdot \frac{1}{2}x-4\cdot 4=4\cdot \frac{3}{4}x$ Simplify. $2x-16=3x$ Subtract $2x$ from both sides. $2x-16-2x=3x-2x$ Simplify. $-16=x$ Hence, the solution to the equation is $\{-16\}$.
