**Answer:**

__Question 1__

The error is in step 2. They have subtracted from the left side of the equation, yet only subtracted 3 from the right side.

__Questions 2 & 3__

Solve:

Apply the distributive law :

Collect and combine like terms:

Subtract 18 from both sides:

Divide both sides by 12:

3 ( 3x + 6 + x ) = 1

Step 1, apply distributive method.9x + 18 + 3x = 1

Step 2, simplify the following12x + 18 = 1

Step 3, Change side12x = -17

Final answerx = -17/12

Theerror/mistake was in step 2where [ 9x +3x = 12x ]Recheck the answer3 ( 3x + 6 + x ) = 1

3 ( 3(-17/12) + 6 + -17/12 ) = 1

1 = 1

Hence proved our solution is correct.
