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
