$x=-20$
$\frac{1}{2}x-5=\frac{3}{4}x$ $\longrightarrow$ addition property of equality $\frac{1}{2}x-5-\frac{1}{2}x=\frac{3}{4}x-\frac{1}{2}x$ $\longrightarrow$ combine like terms $-5=\frac{1}{4}x$ $\longrightarrow$ multiplication property of equality $-5\times4=\frac{1}{4}x\times4$ $\longrightarrow$ simplify $-20=x$
