Answer:

Let's solve the equation step by step to determine how many solutions there are:

4y + 9 = 4y - 7

First, let's get all the variables (y) on one side of the equation. We can do this by subtracting 4y from both sides:

4y - 4y + 9 = 4y - 4y - 7

This simplifies to:

9 = -7.

Now, we can see that we have a contradiction. There is no value of y that satisfies this equation because 9 cannot be equal to -7.

Therefore, the equation has no solutions.

Answer:

No, solution

Explanation:

If you subtract 4y from both sides you are left with

9 = -7 This is a false statement, so there are no solution.
