Answer:
The correct answer is x = 2.
Step-by-step explanation:
To solve this problem, we should first remember that in solving equations, our goal is to get the variable (in this case, x) by itself on one side of the equation. To do this, we must divide both sides of the equation by 9 to get rid of the coefficient on the x term. This is modeled below:
9x = 18
9x/9 = 18/9
x = 2
Therefore, the correct answer is x = 2.
To check your answer, you can always plug the value for x back into the equation. For example, 9(2) = 18 is a true statement, so we know that we got the correct answer.
Hope this helps!
Answer:
x=2
Step-by-step explanation:
You want to get x by itself, in order to do that, whatever you do to one side of the equal sign you have to do it to the other. So you divide 9 by 9 and 18 by 9 and that should leave you with x=2.
9x=18
÷9 ÷9
x=2
