Answer:

x = 12

Step-by-step explanation:

10 - 3 ( x + 7 ) = 26

First Step: Distribute

- 3 to ( x + 7 )

= 10 - 3 x - 21 = 26

Second Step: Combine like terms

10 - 21

= - 11 - 3 x = 26

Third Step: Add from both sides

26 + 11

= - 3 x = 37

Fourth Step: Divide from both sides

37 / - 3

x = 12
