3.2n + 13.3 = 26.1

Answer 1

`n=4`

Explanation:

We start off with 3.2n + 13.3 = 26.1.

We need to get n by itself.

Subtract 13.3 from both sides.

`3.2n+13.3-13.3=26.1-13.3`

`26.1-13.3=12.8`

We end up with:
`3.2n=12.8`

Divide 3.2 on both sides to get n by itself.

`(3.2n)/(3.2) =(12.8)/(3.2)\\ n=4`
