Question

find the pair of linear equations x-3y-3=0 ,3x-9y-2=0 by cross multiplication method​

Answer 1

Answer:

x-3y-3=0

3x-9y-2=0

first solve first equation

1x-3y-3

a1=1, b1=-3, c1=-3

now , solve second equation

3x-9y-2=0

a2=3, b2=-9, c2=-2

a1/a2

=1/3

b1/b2

=-3/-9

=1/9

c1/c2

=-3/-2

a1/a2= b1/b2 ≠ c1/c2

so we don't have any solution
