Justify each step used to simplify the expression. 1. 3x+2y-2x+3=3x-2x+2y+22. =(3x-2x)+2y+23. =(3-2)x+2y+24. =x+2y+2

We have to simplify the given expression:

1.

Combining the like terms,we get the second step as

2.

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

3.

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

4.
