This is the correct answer

Answer 2

Step-by-step explanation:

let the first number = x

second = y

According to given information,

x + y = 75 (1)

x - y = 15 (2)

By solving substitution method ,

x = 75 - y (3)

put value eq 3 in 2

(75 - y) - y = 15

75 -2y = 15

75 - 15= 2y

2y = 60

y = 30

put the value of in equation 3

x = 75 - 30

x = 45

So that the number is 30 and 45
