Hi!

To find the value of n in the given equation, multiply both sides by 3.

That way, you'll clear the fractions and solving for n will be easier.


\implies\boldsymbol{\displaystyle(2)/(3) n*3=-12*3}

Watch what happens:


\implies\boldsymbol{\displaystyle(2)/(\\ot3) n*\\ot3=-36}

On the LHS, the 3's cancel out, and we're left with 2n:


\implies\boldsymbol{2n=-36}

Now, divide both sides by 2:


\implies\boldsymbol{n=-18.}

Voila! There's our solution.

Have a nice day!

I hope this helps.

Answer:

n=-18

Explanation:

Steps:

multiply 3 by both sides of the equation


  1. 3((2)/(3) )=(-12)3

2. cross out the 3 from
3((2)/(3) ) and you will get 2 and then do -12 x 3 and you will get -36.

3. you now have 2n=-36

4. divide both sides by 2 to isolate n by itself.


(2n)/(2) =(-36)/(2)

5. divide by crossing out 2 and 2 on the right and then do -36 ÷ 2 which will give you n= -18

Hope this helps :) if you have any questions let me know.
