# How do you solve and check your solutions to -11=z/-2?

$z = 22$

#### Explanation:

$- 11 = \frac{z}{-} 2$
$\frac{z}{-} 2 = - 11$
multiply both sides $- \frac{2}{1}$
$\left(- \frac{2}{1}\right) \cdot \left(\frac{z}{-} 2\right) = - 11 \left(- \frac{2}{1}\right)$
$z = 22$
sustitute$z = 22$
$- 11 = \frac{22}{-} 2$
$- 11 = - 11$

$z = 22$

#### Explanation:

Let's answer this solve and check this equation step by step

Step 1: Simplify both sides of the equation.
$- 11 = \left(- \frac{1}{2}\right) \cdot z$

Step 2: Flip the equation.
$\left(- \frac{1}{2}\right) \cdot z = - 11$

Step 3: Multiply both sides by $\frac{2}{- 1}$.
$\frac{2}{-} 1 \cdot - \frac{1}{2} \cdot z = \frac{2}{-} 1 \cdot - 11$

$z = 22$
Check solution
$\frac{22}{-} 2 = - 11$
That's means solution is true
