Question

Check whether the following equations are consistent or inconsistent . Solve the graphically. ,s) 3x+2y=8and 3x-3y=1

Answer 1

Answer:

⇒

a

2

a

1



=

b

2

b

1

Hence the system of equations has unique solution.

Thus the pair of equations are consistent

Step-by-step explanation:

Let a

1

x+b

1

y+c

1

=3x+2y−5 and a

2

x+b

2

y+c

2

=2x−3y−7

So, here a

1

=3; b

1

=2; c

1

=−5; a

2

=2; b

2

=−3; c

2

=−7

⇒
