So...you are one of those people who write a question without an image.
Well for now I will answer the question with assumed information.
You are looking for expressions equivalent to 5x-2.
Some sample answers:
-2+5x
x5-2
2(2.5x-1)
[tex]\frac{10x-4}{2}[/tex]
Answer: 2x−2+3x, hopefully, this is the answer that you are looking for.
