-39/3= -13

You would do the opposite of multiplication since x is being multiplied by 3.

The opposite is division. 

All you need to do is balance the equation by dividing the 3 into both sides.

3(/3)x= -39(/3)

"D" is the correct answer.

I hope this helps!

Hey there,

3x =-39 right?

That means three multiplied by x is -39.

So we have to find x here right?

To do that we must isolate x in one side of the equation OK?

So what must we do to just have x on one side if the equation?
We can divide by three right?
That will give us just x one one side right?
So we divide by three and get x.

Now because it is an equation when you do something to one side you must do it to other other side too OK?

That means I you must divide by three on the other side too OK?
So -39 divided by three is -13 right?

Now we have x=-13

And we know exactly what x is,-13
So the answer is d,13

Hope this helps!!
