Question

Find the number of solution for equations x+2y=8 & 2x+4y=16

Answer 1

This is the answer

x-wy-8=0

2x+4y-16=0

here, a1=1 ,b1=2 ,c1=-8

a2=2 ,b2=4 , c2=-16

so, a1/a2 =1/2 = b1/ b2 =2/4 =1/2 ,c1/c2 = -8/-16=1/2

sinc a1 / a2 =b1/b2 =c1/c2 , the pair of linear equations has infinitely many solution

Hope it helps
