Question

rakhi yogam 4 x minus 4 y plus 8 barabar 0 aur 7 guna + 6 y bra bra bra 0 hai​

Answer 1

Answer:

x=-12/13 , y=14/13

Step-by-step explanation:

Given,

4x-4y+8=0 or, 4(x-y)=-8 or, x-y=-2 and

7x+6y=0

doing 1st eqⁿx7 - 2nd eqⁿx1

(7x-7y) - (7x+6y) = -14 - 0

-7y-6y = -14

-13y = -14

y = 14/13.

putting 1st eqⁿ

x-y = -2

x = y-2 = 14/13 -2 = -12/13.
