multiply the parenthesis by -2
-2z-22=6
add 22 to each side.
-2z=28
divide both sides by -2
z=-14
I am having trouble with these kinds of problems and I ask my teacher but he doesnt explain it good enough. Will you please tell me step by step instructions to solve this type of problem...
-2(z + 11)=6
thank you

-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.
