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

\huge\boxed{\text{Solved for x:}\ x=\frac{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{\frac{11}{3}}

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

when they have the same amount.

equate [1] and [2] we get;

Add both sides 2x we get;

Subtract 11 from both sides we get;

Divide both sides by 7 we get;

x = 7

Substitute the value of x = 7 in [1] we have;

Therefore, at x= 7 week they have the same amount of money and they  have the amount at that time, $ 46
