Answer 3

To simplify the expression -7x + 15y + 11x - 21y, you can combine like terms by adding or subtracting them. Like terms are terms that have the same variables raised to the same powers. In this case, you have x and y terms.

-7x + 15y + 11x - 21y

Now, let's group the like terms together:

(-7x + 11x) + (15y - 21y)

Simplify each group:

4x - 6y

So, the simplified expression is 4x - 6y, which corresponds to option б) 4x + 6.
