Question

Solve. 14/n+7=10/n-4

N=5.25
N=3.5
N=31.5
N=30

Answer 1

n=31.5

Explanation:

The given question is:

`(14)/(n+7)=(10)/(n-4)`

Cross multiply to get:

`14(n-4)=10(n+7)`

Expand the parenthesis:

`14n-56=10n+70`

Group similar terms:

`14n-10n=70+56`

Combine the like terms

`4n=126`

Divide both sides by 4

`n=(126)/(4)`

n=31.5
