Question

Add 15 to a number and divide the sum by 5 we get 8.​

Answer 1

Answer:

15+x÷5=8

15+x=8×5

15+x=40

x=40-15

x=25

Answer 2

let number be x

sum of x+15 be y

x+15=y----------(1)

y÷5=8--------(2)

y=8×5

y=40

let put y=40 in eq(1)

x+15=y

x+15=40

x=40-15

x=25

Add 15 to a 25 and divide the sum i.e. 40 by 5 we get 8.
