Question

Find whether the following pair of linear equation is consistent or inconsistent x+3y=5,2x+6y=8​

Answer 1

Answer:

ok x+3y equals to 5 then

x+3y-5equal to zero first equation

now 2x+6y equals to 8 then

2x+6y-8 equal to zero

now on comparing equation 1 and 2

we get that the ratio of a1and a2 is 1/2 and b1/b2 is 3/6 that is 1/2 now c1 / c2 -5/-8 that is not equal to previous equations so it is inconsistent
