Solve for y y=-1/2(2)

$y = - \frac{1}{2} (2)$

Remove parentheses.

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

Cancel the common factor of $2$ .

Move the leading negative in $- \frac{1}{2}$ into the numerator.

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

Cancel the common factor.

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

Rewrite the expression.

$y = - 1$
