Question

Subtract 11x - 4y from the sum of 15x + 15y and - 18x + 15y.

Answer 1

-14x + 34y

Explanation:

First, find the sum of the two expressions by adding like terms:

(15x + 15y) + (-18x + 15y)

= -3x + 30y

Now, subtract 11x - 4y, again by combining like terms:

(-3x + 30y) - (11x - 4y)

= -14x + 34y

So, the answer is -14x + 34y
