Question

How do you solve this equation?

Answer 1

To solve this question, what you would need to do is add 30 to both sides of the equation and then divide by 9, to find the solution.

You can check if it is correct by substituting the same value back into the original equation and seeing if the left hand side is equal to the right hand side.

Answer 2

9x - 30 = 10080
You want to get the X alone, start out easy and move  -30 to the other side of equal sign.
9x -30 +30 = 10080 + 30
Combine Like Terms
9x = 10110
Now divide both sides by 9, 9x divided by 9 is X
X = 1123 1/3
