We have to simplify the given expression:

1.
3x+2y-2x+2

Combining the like terms,we get the second step as

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

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

4.
x+2y+2
