X+y=14 and x-y=4by elimination method ​

Answer»

ANSWER:

GIVEN :

x + y = 14 and x - y = 4

Solution :

⇒ x + y = 14 ... (i)

⇒ x - y = 4 ... (ii)

From equation (i), we get

⇒ x = 14-y ... (iii)

PUTTING this value in equation (ii), we get

(14-y)- y = 4

⇒ 14 - 2y = 4

⇒ 10 = 2y

⇒ y = 10/2

⇒ y = 5 ... (IV)

Putting this in equation (iii), we get

=> x=9

Hence, x = 9 and y = 5.
