Complete the following activity to solve the sumultaneous equations `3x+2y=6` and `2x+4y=12` by Cramer's rule method.
`D=|(3,2),(2,4)|=8, D_(x)=|(6,2),(12,4)|=square, D_(y)=|(3,6),(2,12)|=square,`
`x = square , y = square`.

Text Solution

Verified by Experts

`D_(x)=|(6,2),(12,4)|=24-24= ul(" 0 "),`
`D_(y)=|(3,6),(2,12)|=36-12= ul(" 24 "),`
`x=(D_(x))/(D)=(0)/(8)= ul(" 0 ") , y=(D_(y))/(D)=(24)/(8)= ul(" 3 ")`
