# If the sum of two

Answer :

Let the numbers are X and Y

According to the problem,

X + Y = 84 …. (1)

X – Y = 30 …..(2)

Now minus 2^{nd} equation from 1^{st},

⇒ 2X =84 - 30

⇒ 2X = 54

⇒ X = 54/2

⇒ X = 27

Now put the value of X in the 1st equation,

⇒ X + Y = 84

⇒ 27 + Y = 84

⇒ Y = 84 – 27

⇒ Y = 57

∴ The value of X and Y are 27 and 57
