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?

Respuesta :

Answer:

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
