Step 3.1

Add $1$ to both sides of the equation.

$y = - \frac{1}{2} + 1$

Step 3.2

Write $1$ as a fraction with a common denominator.

$y = - \frac{1}{2} + \frac{2}{2}$

Step 3.3

Combine the numerators over the common denominator.

$y = \frac{- 1 + 2}{2}$

Step 3.4

Add $- 1$ and $2$ .

$y = \frac{1}{2}$

Step 4

The result can be shown in multiple forms.

Exact Form:

$y = \frac{1}{2}$
