Question

If am is not equal to bl,then the pair of linear equations ax+by=c and lx+my=n​

Answer 1

Answer:

Evolution is the change in the heritable characteristics of biological populations over many generations. The basic concept of evolution is that the populations and species of organisms changes over time.

Answer 2

Given that am



=bl

⇒

l

a



=

m

b

We know that if a

1

x+b

1

y+c

1

=0 and a

2

x+b

2

y+c

2

=0

is a pair of linear equations in two variables x and y such that

a

2

a

1



=

b

2

b

1

, then the pair of linear equations is consistent with unique solution.

Hence, given pair of equations has a unique solution.
