Question

वज्रगुणन विधि से हल करें 5x +3y = 10 और 2x +4y = 28​

Answer 1

Firstly please tell me what is vrijgunan Vidhi

Answer 2

Answer:

2(5x + 3y = 10)

10x + 6y = 20-----(i)

5(2x + 4y = 28)

10x + 20y = 140-------(ii)

Equating (i) & (ii)

we get

-14y = -120

y = 60/7

Put y value in (i)

we get,

      10x = 140-360/7

      10x = -220/7

          x = -22/7
