Question

2x-y=6 and x-y=2 solve by cross multiplication ​

Answer 1

Answer:

2x−y−6=0 .......(1)

x−y−2=0 ......(2)

We know, according to cross-multiplication method,

2−6

x

=

−6+4

y

=

−2+1

1

−4

x

=

−2

y

=

−1

1

On equating first and third expression, we get

x=4

and, on equating second and third expression, we get,

y=2
