Answer 2

Answer:

33,12

Step-by-step explanation:

let one no be x

let another no be y

according to question,

x+y = 45

so x= 45-y......(1)

also, x-y = 21

and 45-y -y = 21 (substituting the value of x from equation (1))

= 45-2y = 21

= 2y = 45-21

= 2y = 24

so y = 24/2 = 12

so, x= 45-y = 45-12= 33

so, first no= 33

so, first no= 33second no = 12
