3 times x = 3x, 3 times 2 = 6, so therefore
3x + 6 = 18
3x = 12
x = 12 / 3
x = 4

First, you would have to use the distibutive property on one side of the equation to get risd of the parentheses. 3(x+2) =18 becomes 3x+6=18.
Then, subtract 6 from both sides and the result is 3x =12.
Then, you would have to divide both sides of the equation by 3. Remember that whatever you do to one side, you would have to do to the other.
The answer to this problem is 3(4+2) =18.
Remember to check your work at the end of each problem!

3(x+2)=18 > multiply 3 time x, then 3 times 2
so 3x+6=18, subtract 6 from each side
3x=12 divide each side with 3, x-4

3(x+2) = 18
3(x+2)/3 = 18/3
x+2 = 6
x+2-2 = 6-2
x=4

divide by 3 both sides
x+2=18/3
x+2=6
substract 2 both sides
x=6-2
x=4

IF you're wanting ot find what x is, this is the answer and what you need to know how to do so next time you don't have to post the question on Yahoo Answers!!: Divide 18 by 3. Now that you have that answer, subtract 2 from that answer. This is what x is. x=4!!! Hope I helped!!!
