Question

On comparing the ratios of the coefficients, find out whether the pair of
equations x - 2y =0 and 3x + 4y -20 =0 is consistent or inconsistent.​

Answer 1

Step-by-step explanation:

Given

3x−4y=7.........eq(1)

x+cy=13..........eq(2)

We know that,

If the system of equations have no solution then,

a2

a1

=

b2

b1



=

c2

c1

so,

a2

a1

=

b2

b1

⇒

x

3x

=

cy

−4y

⇒3c=−4

c=−

3

4
