The correct option is A inconsistent
Given, 4x+y=23 and 8x+2y=10
The general form for a pair of linear equations in two variables x and y is:
a1x+b1y+c1=0 and
4x+y=23---(1)
8x+2y=10---(2)
Comparing equations (1) and (2) with the general form of equation to consider their co-efficient,
a1=4 , a2=8 , b1=1 , b2=2 , c1=23 , c2=10
Now, ratio of coefficient => 48=12≠2310
We know that when a1a2=b1b2≠c1c2 then equations are said to be inconsistent.
Hence, the equations are inconsistent.
