Question

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`

 

Solution

`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 `

  Is there an error in this question or solution?
