Question

How many solutions does 9x+7=9x-4 have A) one solution B) No solution or C) infinitely many solutions.

Answer 1

No Solution

Explanation:

If we solve for the equation, we get a statement that isn't true.

9x + 7 = 9x - 4

-9x -9x

----------------------

7 = - 4

*subtract 9x from both sides*

We know that 7 ≠ -4, so there aren't any solutions to this problem.

Hope this helped!
