Answer:

infinite number of solutions

Step-by-step explanation:

Given

- 4n + 9 = - 2(2n - 1) + 7 ← distribute and simplify right side

- 4n + 9 = - 4n + 2 + 7

- 4n + 9 = - 4n + 9

Since both sides are equal then any value of n makes the equation true.

That is there are an infinite number of solutions
