The expression 4x - 3y - 5x - 2y can be simplified by combining like terms. Like terms have the same variables raised to the same powers. In this case, the x terms are like terms and the y terms are like terms. Combining the x terms, we get -x, and combining the y terms, we get -5y. Therefore, the simplified expression is -x - 5y.
No. For purposes of combining "like terms", you need terms that have exactly the same variables, with the same exponents (if there are any).
You add (or subtract) like terms. This will reduce the number of terms in the expression and that is the extent of simplification that you can achieve using this process.

When you have an expression you have to simplify by eliminating all grouping symbols and combining like terms.
