    Let the number of students in the class be x

    Let the number of pieces of gum she gave out be 3x

    Equation

    3x + 8 = 168 This will not work out evenly. Let's try x - 1. The reason for that is because she may not give out anything to herself.

    3 (x - 1) + 8 = 168 This doesn't work either.

    Well we have to choose. It's a rounding problem.

    3x + 8 = 168 Subtract 8 from both sides.

    3x = 168 - 8 Combine

    3x = 160 Divide by 3 on both sides.

    x = 160 / 3

    x = 53.333333333

    Since that can't be, we could say there were 53 students.

    3x
