Question

on comparing the ratios of the On comparing the ratios of the coefficients, find out whether the pair of
equations x + 2y+5 =0 and -3x -6y+1=0is consistent or inconsistent.

please solve this question​

Answer 1

Step-by-step explanation:

inconsistent as the co efficient of x,y are in proportion but

constants are not in proportion

x+2y+5=0

coefficients of x,y = 1,2 =1:2

-3x-6y+1=0

coefficients of x,y =-3,-6=-3:-6=1:2

but constants 5:1 not in same proportion
