Question

Please help me answer this

Answer 1

Hello!

Answer:

$\boxed{ \bf x=6}$

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.

$\frac{3x}{3} = \frac{18}{3}$

x = 6

Answer 2

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.

• $\frac{3x}{3} =\frac{9}{3}$

5. Simplify.

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

Therefore, your answer is X = 3
