For this you have to write an equation:
3x-2=9

Step-by-step explanation:
2- [two less than]
3x [three times a number, we will use X as the number]
= 9 [is nine]

When writing an equation you typically want to put the variables first and all other terms afterwards.

Solving:
3x-2=9
+2 +2 move 2

3x=11
——— divide by 3 to get X by itself
3

x= 11/3 or x= 3.6

\huge\boxed{\text{As an expression:}\ 3x-2=9}


\huge\boxed{\text{Solved for x:}\ x=(11)/(3)}

Let's start with "
3 times a number". We will use
x to represent the number.
3x

"
2 less than" is next.
-2

Finally, "is
9".
=9

Put it all together to get an expression.
\boxed{3x-2=9}

Now, let's solve for the unknown number.

Add
2 on both sides of the equation.
3x=11

Divide both sides of the equation by
3 to isolate
x.
x=\boxed{(11)/(3)}
