Students at a school were able to choose whether they wanted to take a sports class for physical education of a dance class. The 274 students who chose sports class represented 38 less than two times the number
of students who chose dance class. How many students chose dance class?

156

Step-by-step explanation:

Let d = people who chose dance class

274 = 2d - 38

Add 38 to both sides

274 = 2d - 38

+ 38       + 38

312 = 2d

Divide both sides by 2

312/2 = 2d/2

d = 156
