Explanation:

We have to simplify the given expression:

1. 3x+2y-2x+23x+2y−2x+2

Combining the like terms,we get the second step as

2. (3x-2x)+(2y)+(2)(3x−2x)+(2y)+(2)

Now, taking 'x' common from the first two terms, we get third step as:

3. (3-2)x+2y+2(3−2)x+2y+2

Now, simplifying the expressions among the like terms, we get fourth step as:

4. x+2y+2x+2y+2
