Question

Need help with simplifying expressions

Answer 1

The answer is -20

I know it looks hard, but all you need to do is combine like terms.

Here’s an example:

4x+5x=18

4x plus 5x equals 9x. So your equation is now-

9x=18

Now you just divide 18 by 9

which is 2, and you just drop the x

Hope this helps

Answer 2

Answer:

A) -20

Step-by-step explanation:

distribute the 4y and the -4 to the parentheses

16y^2 -16y+16y-20-16y^2

combine like terms

16y^2-16y^2=0

-16y+16y=0

-20
