There were 3 times as many adults as students attending a school play. If the attendance was 480, how many adults and how many students attended the play?

Let x equal the number of students attending the school play and solve this equation.

3x + x = 480

First, you need to combine like terms.

4x=480

Then, divide each side by 4.

4x/4=480/4

4's on the left side cancel out, leaving:

x=120

Adults(3x):360
Students(x):120
