Answer 2

Answer:

Question :-

x + y = 8

x - y = 4

Answer :-

x + y = 8...(1)

x - y = 4...(2)

By multiplying (1) 1 and (2) 1

x + y = 8

x - y = 4

---------------

2x = 12

➻ x = 12/2

➻ x = 6

By putting the value of x in the equation no 1 we get,

➻ x + y = 8

➻ 6 + y = 8

➻ y = 8 - 6

➻ y = 2

∴ The value of x = 6 , y = 2
