Work Step by Step

Subtract $\frac{3}{4}$ from both sides 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. (-$\frac{21}{4}$)+$\frac{3}{4}$=-$\frac{9}{2}$ -$\frac{18}{4}$=-$\frac{9}{2}$ -$\frac{9}{2}$=-$\frac{9}{2}$
