Answer: 659x.
Step-by-step explanation:I think you mean 2x but here's how to do it.
So you have to remember an important phrase. Combine like terms. All that means is that terms that are alike go together.
Ex. 2 goes with 4, 83y goes with 26y
So basically you are adding it like it's a normal addition equation.
So, 2x + 657x=659x.
