$z = 22$ $z=22$

Explanation:

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

$z = 22$ $z=22$

Explanation:

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

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

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

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

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