Question

Simplify 3n-(n+4) I am having trouble with it

Answer 1

Alrighty. We can simplify using properties. Do you know what these are? please get back to me.

Answer 2

The answer is 2n - 4.
This is the answer because behind that minus sign is a one. If you distribute that -1 after you distribute the -1 you get 3n - n - 4. Then simplify that you get 2n - 4
