Can anyone explain this in 50 words why the equation turns out like it does?

-6x-18=-6x+5 0x=23 and can not have zero in the denominator. Division by zero is undefined.

15x+18=15x+18 0x=0 Well, if you take anything times zero the resulting product is zero.

This is the third time that you have posted this question

Don't you ever read your own posts ?

The equation you provided is -6x-18=-6x+5. To understand why it turns out like it does, we can simplify it step by step. First, we group the terms with x on one side and the constant terms on the other side. By adding 6x to both sides of the equation, -6x and -6x cancel out, leaving -18=5. However, this equation is not possible since -18 and 5 are not equal. Therefore, there is no solution to this equation.
