Question

Steph age is 7/5 times of the total of students in this class minus 22. If steph is 13 years old , write an equation to find the total students in the class.​

Answer 1

Explanation:

Let us take:

Steph's age = x

No. of students in the class = y

Given that,

x = 13

also,

x = 7/5y - 22

That gives,

13 = 7/5y - 22

13 + 22 = 7/5y

35 = 7/5y

35 × 5/7 = y

5 × 5 = y

25 = y
