Answer 2

Solving the Equation 9x-21=9x+18

To solve the equation 9x - 21 = 9x + 18, we can start by simplifying the equation and then determining if there is a solution.

First, let's simplify the equation by moving the variable terms to one side and the constant terms to the other side.

Step 1: Subtract 9x from both sides of the equation: ``` 9x - 9x - 21 = 9x - 9x + 18 -21 = 18 ``` After simplifying, we get -21 = 18, which is not a true statement. This means that the equation has no solution.

Therefore, the solution to the equation 9x - 21 = 9x + 18 is no solution.
