Question

How do you solve `8/(n+4)=6/2`?

Answer 1

`n=-4/3`.

Explanation:

Given eqn, `8/(n+4)=6/2 rArr 8/(n+4)=3`

Now, multiply on both side by `(n+4)` to get,

`8=3(n+4) rArr 8=3n+12`

Adding `-12` on both side, we get, `8-12=3n`

`:. -4=3n`

Finally, multiply the eqn. by `1/3`, to find the soln. `n=-4/3`.
