x-2y=0 Therefore,a=1,b=-2 3x+4y=20 Therefore,a=3,b=4 a1/a2is not equal to b1/b2 1/3 is not equal to -2/4 In graph intersect each other at same point Therefore,it is consistent

x – 2y = 0

3x + 4y - 20 = 0

1/3 ≠ −2/4

As, a₁/a₂ ≠ b₁/b₂ is one condition for consistency. Therefore, the pair of equations is consistent.
