Question

which of the following pairs has any unique solution a) 2X + Y = 3 and x+2y=5
b)2X+4y=6 and 4X+8y=12 c)4x+8y=14 and 18x
+16y-9=0
d) x+5y-3=0 and 3x+15y-9=0
​

Answer 1

Step-by-step explanation:

Unique solution when both lines intersect at one point it's inconsistent system

condition:A1/A2=B1/B2 not equal to c1/C2

Let u check in option and find the Answer

1) Nothing is equal not unique

2)all are equal not unique

3)nothing is equal (ratio) not an unique

4) everything is equal (ratio) not unique

I think u could done mistake in giving options some where...

Alright u understood concept it seems go ahead with that
