Answer

$ x=-\frac{4}{5}$.

Work Step by Step

The given expression is $\Rightarrow \frac{2}{3}(x+5)=\frac{1}{4}x+3$ Multiply by the LCD $=12$. $\Rightarrow 12\left [\frac{2}{3}\left (x+5\right ) \right]=12\left ( \frac{1}{4}x+3 \right )$ Use distributive property. $\Rightarrow 12\left [\frac{2}{3}\left (x+5\right ) \right]=12\left ( \frac{1}{4}x\right )+12(3) $ Simplify. $\Rightarrow 8\left (x+5\right )=3x+36 $ Use distributive property. $\Rightarrow 8(x)+8(5)=3x+36 $ Simplify. $\Rightarrow 8x+40=3x+36 $ Add $-3x-40$ to both sides. $\Rightarrow 8x+40-3x-40=3x+36-3x-40$ Simplify. $\Rightarrow 5x=-4$ Divide both sides by $5$. $\Rightarrow \frac{5x}{5}=-\frac{4}{5} $ Simplify. $\Rightarrow x=-\frac{4}{5}$.
