Find Cramer's Rule 7y+2x=11,3x-y=5 [ Calculator, Method and examples ]

Solution:
Your problem `->` Cramer's Rule 7y+2x=11,3x-y=5


The equations can be expressed as
`2x+7y-11=0`

`3x-y-5=0`

Use Cramer’s Rule to find the values of x, y, z.
`(x)/D_x=(-y)/D_y=(1)/D`

`D_x` = 
 `7`  `-11` 
 `-1`  `-5` 


`=7 × (-5) - (-11) × (-1)`

`=-35 -11`

`=-46`


`D_y` = 
 `2`  `-11` 
 `3`  `-5` 


`=2 × (-5) - (-11) × 3`
