Answer

x=$\frac{21}{4}$

Work Step by Step

Add $\frac{3}{4}$ to each side of the equation to isolate the variable. x-$\frac{3}{4}$=$\frac{9}{2}$ x=$\frac{9}{2}$+$\frac{3}{4}$ x=$\frac{18}{4}$+$\frac{3}{4}$ x=$\frac{21}{4}$ Check the answer. $\frac{21}{4}$-$\frac{3}{4}$=$\frac{9}{2}$ $\frac{18}{4}$=$\frac{9}{2}$ $\frac{9}{2}$=$\frac{9}{2}$
