Answer:

#z=22#

Explanation:

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

Step 1: Simplify both sides of the equation.
#-11=(-1/2)*z#

Step 2: Flip the equation.
#(-1/2)*z=-11#

Step 3: Multiply both sides by #2/(-1)#.
#2/-1*-1/2*z=2/-1*-11#

#z=22#
Check solution
#22/-2=-11#
That's means solution is true
