An equilateral triangle has 3 congruent sides so the 2 expressions above are equal
3x - 9= 23 - 5x
And then you solve for x
-22=-2x
X=11

Answer:

A

Step-by-step explanation:

The additive inverse property states that if we have a number a, then:

$a+(-a)=0$

Here, we have the equation:

$2x=542$

And we divide both sides by 2:

$2x/2=542/2$

To acquire:

$x=271$

So, we did <em>not</em> use the additive inverse property since we didn't add anything.

Instead, we used the<em> division property of equality</em> by dividing both sides by 2.

So, our answer is A.

And we're done!

(Say I'm righting to sasha)

Hi Sasha! I understand this math is hard,but I'm here to help. 9 goes on top of 14!

If we put 14 on top of 9 it would be an inproper fraction,that's when a fraction is not very easy to work with. Now, we could do 9÷14. :)

Hope dis helps!
