$x = \frac{19}{6}$

Next, use the negative value of the $\pm$ to find the second solution.

$x + \frac{1}{2} = - \frac{11}{3}$

Move all terms not containing $x$ to the right side of the equation.

Subtract $\frac{1}{2}$ from both sides of the equation.

$x = - \frac{11}{3} - \frac{1}{2}$

To write $- \frac{11}{3}$ as a fraction with a common denominator, multiply by $\frac{2}{2}$ .

$x = - \frac{11}{3} \cdot \frac{2}{2} - \frac{1}{2}$

To write $- \frac{1}{2}$ as a fraction with a common denominator, multiply by $\frac{3}{3}$ .

$x = - \frac{11}{3} \cdot \frac{2}{2} - \frac{1}{2} \cdot \frac{3}{3}$

Write each expression with a common denominator of $6$ , by multiplying each by an appropriate factor of $1$ .

Multiply $\frac{11}{3}$ by $\frac{2}{2}$ .

$x = - \frac{11 \cdot 2}{3 \cdot 2} - \frac{1}{2} \cdot \frac{3}{3}$
