Answer:

x = 12.1

Step-by-step explanation:

20 − (z + 7) = 0.9

Distribute the minus sign

20 -x -7 = .9

Combine like terms

13 -x = .9

Subtract 13 from each side

-x = -12.1

x = 12.1

Answer:

20 - (z + 7 ) = 0.9

20 - z - 7 = 0.9

13 - z = 0.9

- z = 0.9 - 13

-z = - 12.1

Divide both sides by -1

z = 12.1

Hope this helps.
