Question

WHAT ARE THE TWO NUMBERSWHOSE SUM IS 58 AND DIFFERENCE IS 28

Answer 1

★ Solution :

Let tge two number be x and y respectively.

x + y = 58 ......(1)

x - y = 28 .......(2)

From equation 1.

x = 58 - y

Put value of x in equation 2.

→ 58 - y - y = 28

→ 58 - 2y = 28

→ -2y = 28 - 58

→ -2y = -30

→ 2y = 30

→ y = 30/2

→ y = 15

$\Large{\implies{\boxed{\boxed{\sf{y = 15}}}}}$

$\rule{200}{2}$

Put Value of y in equation 1.

→ x + 15 = 58

→ x = 58 - 15

→ x = 43

$\Large{\implies{\boxed{\boxed{\sf{x = 43}}}}}$

$\therefore$ Two numbers are 43 and 15 respectively.
