Hey there!
First, let's make an equation. We will use x to represent our secret number. Remember, when making equations, the word is always means an equal sign.
2x+6=3x-14
Now, we put both variables on one side.
-x+6=-14
We put both constants on one side
-x=-20
We divide both sides by -1.
x=20
Our secret number is 20.
I hope this helps!
