Answer: x = 3

Step-by-step explanation:

1. Distribute.

  • 3(x+3)=18
  • 3x+9=18

2. Subtract 9 from BOTH sides.

  • 3x+9-9=18-9

3. Simplify.

  • Subtract 9 from BOTH sides.
  • 3x=9 is the answer.

4. Divide BOTH sides of the equation by the same term.


  • (3x)/(3) =(9)/(3)

5. Simplify.

  • Cancel out the terms that are both in the numerator and the denominator.
  • Divide the numbers.

Therefore, your answer is X = 3

Hello!

Answer:


\boxed{ \bf x=6}

Step-by-step explanation:

3(x + 3) = 18

⇒ Step 1 - Multiply everything in the brackets by 3:

3x + 9 = 18

Step 2 - Subtract 9 from both sides of the equation:

3x + 9 = 18

- 9 - 9

3x = 18

Step 3 - Divide both sides of the equation by 3.


(3x)/(3) = (18)/(3)

x = 6
