(? x 3) - 3 = 15<br><br>help pls and i need the steps :/

Answer:

Step-by-step explanation:

Lets make $x$ be the ? in the equation.

That becomes ( $x$ x 3) - 3 = 15.

First you have to add 3 on both sides. After doing that it gets to ( $x$ x 3) = 15 - 3.

Then you simplify it to 3 $x$ = 12.

Now you divide 3 on both sides. That gets to $x$ = 4 after doing it.

Hope this helped! If not, please let me know! <3
