Question

How many solutions does 9x+5=9x+7

Answer 1

There are 0 solutions to this problem because it cannot be re-arranged logically enough to come to a new conclusion.

Answer 2

0

Explanation:

If we try to solve this question, we get no solutions:

First we subtract 5 from both sides :

9x = 9x + 2

Now we subtract 9x from both sides :

0 = 0 +2

0 = 2 ❌

This is why this equation has no solutions

Hope this helped and have a good day
