Question

what is the answer to 35=-7[z+8]

Answer 1

z=−13 would be your answer

Answer 2

I guess you need to solve for z:

-7(z+8) = 35
First, let's develop -7(z+8):
-7(z+8) = -7z -56

So -7(z+8) = 35
-7z - 56 = 35

Then we add 56 in both sides so we can get the variable on a side and the numbers on another:
-7z - 56 + 56 = 35 + 56
-7z = 91

Then divide each side by -7 so we can get the variable z alone on a side and its value on another side:
-7z = 91
(-7z)/-7 = 91/-7
z = -13

You can re-check your answer (very important):
-7(z+8) = -7(-13+8) = -7 * -5 = 35 (Multiplying negative numbers gives a positive number).
The answer has been approved.

Hope this Helps! :)
