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

[tex]\huge\boxed{\text{Solved for x:}\ x=\frac{11}{3}}[/tex]

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

"[tex]2[/tex] less than" is next. [tex]-2[/tex]

Finally, "is [tex]9[/tex]". [tex]=9[/tex]

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

Now, let's solve for the unknown number.

Add [tex]2[/tex] on both sides of the equation. [tex]3x=11[/tex]

Divide both sides of the equation by [tex]3[/tex] to isolate [tex]x[/tex]. [tex]x=\boxed{\frac{11}{3}}[/tex]

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

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
