-2(z + 11)=6

thank you
Answered by bobpursley
multiply the parenthesis by -2

-2z-22=6
add 22 to each side.
-2z=28
divide both sides by -2
z=-14

-2(z + 11)=6

First, multiply:

-2z - 22 = 6

Then, to combine like terms, add 22 to both sides of the equation.

-2z - 22 + 22 = 6 + 22

-2z = 28

z = -14

You can prove this answer by substituting -14 for z in your original problem.
