That's not an equation, it doesn't ask a question, and it's not looking for a solution.
Your teacher may have given it to you, and asked you to simplify it. Here's
how to 'solve' that assignment:
3x + 5 + 2x + 1
Add up all the 'x' terms: 3x + 2x = 5x
Add up all the number terms: 5 + 1 = 6
The original expression is equal to [ 5x + 6 ].
