Hey there!
The answer to your question is infinitely many solutions.
First, we will simplify each side of the equation. On the left side, we are given:

First, distribute 
:

Add 
 and 
:

On the right side, we are given:

So, we subtract 
 from 
:

Now, we have:

First, subtract 
 from both sides:

We got, 
, which means 
 has infinitely many solutions.
Have a terrificly amazing day! :)
