Question

What is the simplified form of 4r + 5s – 16r + 3s?

Answer 1

Hello!

You can only combine numbers with the same variable

4r - 16r = -12r
5s + 3s = 8s

The answer is -12r + 8s

Hope this helps!

Answer 2

Hello, there!

We must combine like terms.

4r and -16r are like terms.

4r + (-16r) = -12r

5s and 3s are like terms.

5s + 3s = 8s


Our final answer is -12r + 8s


I hope I helped!
