प्रश्न
Complete the following activity to solve the simultaneous equations
3x + 2y = 6 and 2x + 4y = 12 by cramer's method.
`D = [[ 3,2] ,[2, 4 ]] = 8 Dx = [[6,2],[12,4]] = square , Dy = [[3,6],[2,12]] = square x= square y = square`
उत्तर
`D = 8 , x = (Dx)/D = 0/8 = 0 =24 - 24 = 0 , D , = 36-12=24`
`x = (Dx)/D = 0/8 = 0`
`y = (Dy )/D = 24/8 =3 `
