Question

For simultaneous equation in variables x and y, Dx = 49, Dy = - 63, D = 7 than what is x? *​

Answer 1

Step-by-step explanation:

by using Cramer's rule,

x=Dx/D

x=49/7

x=7

Answer 2

Given that,

Dx=49 and Dy=63 and D=7

By using cramer's rule

X=Dx/D

=49/7

=7

Hence the value if X=7
