Question

The pair of coincident lines in the following are:
a)x-2y=0
3x+4y=20
b)2x+3y=9
4x+6y=18
c)x+2y=4
2x+4y=12
d)x+y=8
x-y=4​

Answer 1

Answer:

B) 2x+3y=9 4x+6y=18

Step-by-step explanation:

A1/A2 = B1/B2= C1/C2 is coincident line.

2x+3y-9=0 4x+6y-18=0

Therefore, 1/2 = 1/2= 1/2 :: X = The option B is the pair of equation which have COINCIDENT LINE
