There is only one variable, since you only need to find one unknown quantity. I think you meant to ask, "If we sell 252 tickets, then how many people are in the group?" Am I right?

Let x = the number people in the group.
Your sentence says 9% of the members buy tickets (which equals 252), so

To solve for x, you need to divide both sides by .09:

Next, multiply numerator and denominator by 100 to clear the decimal from the denominator.
people in the group.
