Question

on comparing the ratios of the coifficients find out wheather the pair of equations x-2y=0 and 3x+4y-20=0 is consistent or inconsistent​

Answer 1

Step-by-step explanation:

x-2y=0

comparing with a1x+b1y+c1=0

a1-= 1,b1= -2

3x+4y-20=0

comparing with a2x+b2y+c2=0

a2=3, b2=4

a1/a2= 1/3

b1/b2 = -2/4 = -1/2

here a1/a2 not equal to b1/b2

therefore it's consistent
