liberstina [14]

Answer:

<em>B) x = 3</em>

Step-by-step explanation:

lets plug in the first option to see if it works

3x=9

3*27=9

<em>thats not right</em> ( 3*27 = 81 )

Next, we try the second option

3x=9

3*3=9

<em>that looks more like a resonable answer right?</em>

<em>now to check our work</em>

3+3+3=9

<em>Its correct!</em>

<em>Hope that helps</em>

May~
