Question

a spanish class has a total of 46 students. the number of males is 4 more than the number of females. how many males and how many females are in the class?

Answer 1

There are 25 males and 21 females in the class

Explanation:

Let us use the equation to solve the question

∵ A Spanish class has a total of 46 students

∵ The number of males is 4 more than the number of females

→ Assume that the number of females is x

∵ The number of females = x

∴ The number of males = x + 4

→ Add the numbers of males and females and equate the sum by 46

∴ x + x + 4 = 46

→ Add the like terms in the left side

∴ 2x + 4 = 46

→ Subtract 4 from both sides

∴ 2x + 4 - 4 = 46 - 4

∴ 2x = 42

→ Divide both sides by 2

∴
`(2x)/(2)=(42)/(2)`

∴ x = 21

∵ x represents the number of females

∴ There are 21 females

∵ x + 4 represents the number of males

∴ The number of males = 21 + 4 = 25

∴ There are 25 males
