Question

How do you solve `5/6=(7n+9)/9`?

Answer 1

`n = color(green)(-3/14)`

Explanation:

Given
`color(white)("XXX")5/6=(7n+9)/9`
Multiplying both sides by `18` to get rid of the denominators
`color(white)("XXX")15=14n+18`

Rearranging and simplifying
`color(white)("XXX")14n=-3`

`color(white)("XXX")n=-3/14`
