Answer:
x=2
Explanation:
9x=18
To solve for X we need to have just X on one side. We can do this by dividing each side by 9. Which is equal to the original because we are dividing by the same thing on both sides.
9x/9=18/9
This simplifies to x=2
We can check by putting 2 back into the equation:
9(2)=18
And that is true so we know we have a correct answer.
