Answer 2

It looks like you've provided an expression:

-66x + 20y - 17x + y

This expression can be simplified by combining like terms. Like terms are terms that have the same variable(s) raised to the same power(s). In your expression, you can combine the x and y terms:

-66x - 17x + 20y + y

Now, let's combine the x terms and the y terms separately:

-66x - 17x = -83x 20y + y = 21y

So, the simplified expression is:

-83x + 21y
