Answer:

x= - 1   ; z = - 9

Step-by-step explanation:

The requester asked for 8 and 11, but I can't see the problem in the picture.

Here are 7 and 10:

#7 5x - 4x + 2 = 1

Combine 5x and -4x to get x

x + 2 = 1

Subtract 2 from both sides

x = -1

#10 -40/2 = z - 11

Simplify -40/2 to get -20

-20 = z - 11

Add 11 to both sides

z = -9

If you want 8 and 11, reupload the problem with a picture that includes them.
