Question

The pairs of equations x+2y-5 = 0 and -4x-8y+20=0 have: ​

Answer 1

Answer:

infinitely many solutions

Step-by-step explanation:

divide the second equation by -4 throughout. both lines are identical

Answer 2

Answer:

hy mate..

Step-by-step explanation:

we can identify it by taking the ratios of the coefficients of the equations...

a1 / a2 =b1 / b2 =c1/c2

here, a1 = 1 , a2=-4 ; b1=2, b2=-8 ; c1=5,c2=-20

1/-4 = 2/-8 =5/-20

1/-4 = 1/-4= 1/-4

therefore we get dependent and consistent solutions..
