Question

PLEASE HURRY: A biology class has a total of 31 students. The number of females is 17 less than the number of males. How many males and how many females are in the class?

Answer 1

7 females, 24 males

Explanation:

I solved it by using this equation:

2x + 17 = 31

then, i subtracted 17 on both sides:

2x=14

then divide by 2 on both sides:

x=7

then I added 7 to 17 to find the number of males:

7+17= 24
