Question

2x+3y-9 =0 and 4x+6y-18=0 this pair of liner equations have _____ solution​

Answer 1

Answer:

Infinite Number of Solutions

Step-by-step explanation:

Because

$\frac{a1}{a2} =\frac{b1}{b2} =\frac{c1}{c2} \\\\\frac{2}{4} =\frac{3}{6} =\frac{-9}{-18} \\\\\frac{1}{2} =\frac{1}{2} =\frac{1}{2}$

Answer 2

Answer:

The given system of solutions have Infinite number of solutions.

From above pair of linear equations ,

a1 = 2 , b1 = 3 , c1 = -9

a2 = 4 , b2 = 6 , c2 = -18

a1/a2 = 2/4 = 1/2

b1/b2 = 3/6 = 1/2

c1/c2 = -9/-18 = 1/2

a1/a2 = b1/b2 = c1/c2

Therefore, The given system of solutions have infinite number of solutions,
