N - 3n = 14 - 4n what is it?

N - 3n = 14 - 4n

Combine like terms on the left. (Like terms being things with the same variables brought to the same power ... so x^2 and x wouldn't be a like term. While n and 3n are like terms)

- 2n = 14 - 4n

Add 4n on both sides to remove the - 4n from the right and get all n terms on the left.

- 2n + 4n = 14 - 4n + 4n

- 2n + 4n = 14 + 0

- 2n + 4n = 14

Combine like terms on the left side!

2n = 14

Divide 2 on both sides to cancel out the 2 on the left. (Canceling out is simply making it equal 1. For example, 3/3 = 1. This can also work for variables, because the variables will both be the same. Example, n/n = 1. Because n can only equal 1 number at a time. So say if n = 3. 3/3 = 1)

2n/2 = 14/2

n = 7
