Question

×+y=65 व ×-y=35 तर ×व y ची किंमत काढा​

Answer 1

Step-by-step explanation:

Soln:-

Given,

x + y = 65,------- equation 1

x - y = 35------- equation 2

Now,

x + y = 65

=> x. = 65- y -----equation 3

Now putting equation 3 in equation 2

x - y = 35

=> (65 - y) - y = 35

=>65 - 2y. = 35

=> 65 - 35. = 2y

=> 30. = 2y

=> y. = 30/2

=> y = 15.

Now ,

x + y = 65

=> x +. 15 = 65

=> x. = 65 - 15

=> x = 50

so,

x=50

y=15
