How many solutions does this equation have? 18z + 7 = –20 + 18z + 15

This equation has no solution.

Step-by-step explanation:

When you are in the process of solving this, you combine like terms and end up with 18z + 7 = 18z -5. When there is a common term on both sides, you cancel it. So in this case you would cancel the 18z on both sides. Then you would be left with 7 = -5, which is a false statement. 7 is not the same as -5. Therefore this equation does not have any solutions. Hope this helps.
