What value of n makes the equation true 2/3 n= -12
muminat

Answer:

The answer is - 18

Step-by-step explanation:

\frac{2}{3} n =  - 12

To solve the equation multiply both sides of the equation by 3

That's

<h3>3 \times  \frac{2}{3} n =  - 12 \times 3</h3>

Simplify

<h3>2n =  - 36</h3>

Divide both sides of the equation by 2

<h3 /><h3>\frac{2n}{2}  =  \frac{ - 36}{2}</h3>

We have the final answer as

<h3>n = - 18 </h3>

The value of n that makes the equation true is - 18

Hope this helps you
