a math class has a total of 42 students. The number of males is 8 more than the number of females. How many males and how many females are in the class?​

Respuesta :

Answer:

25 males and 17 females.

Step-by-step explanation:

If the number of males is x and the number of females = y, we have the system:

x + y = 42

x  = y + 8

Substituting for x in the first equation:

y + 8 + y = 42

2y = 42 - 8 = 34

y = 17.

and x = 17+8 = 25.
