Answer:
<u>x = 12</u>
Step-by-step explanation:
10 - 3 ( x + 7 ) = 26
<em>First Step: Distribute</em>
- 3 to ( x + 7 )
= 10 - 3 x - 21 = 26
<em>Second Step: Combine like terms</em>
10 - 21
= - 11 - 3 x = 26
<em>Third Step: Add from both sides</em>
26 + 11
= - 3 x = 37
<em>Fourth Step: Divide from both sides</em>
37 / - 3
<u>x = 12</u>
