Question

Find out whether the pair of linear equation 3x-6y-7= 0 and 12x-24y-5=0 are consistent,or inconsistent​

Answer 1

Answer:

a1=3 and a2=12

b1=-6 and b2=-24

c1=7 and c2=5

a1/a2=3/12=1/4

b1/b2=-6/-24=1/4

c1/c2=7/5

Hence,a1/a2=b1/b2 not= c1/c2

therefore,these linear equations are parallel to each other and thus have no possible solution. Hence,the pair of linear equations is inconsistent.
