Answer:
Step-by-step explanation:
solution 2)
the linear pair of equations has a unique solution that means
a1/a2 is not equal to b1/b2
5x-ky-15=0 here a1=5 ,a2=-k and c1 = -15
x+5y-15=0 here a2=1, b2= 5 and c2 = -15
a1/a2=5/1
b1/b2=-k/5
5 is not equal to -k/5
or 25 is not equal to -k
or k is not equal to -25
solution 3)
the linear pair of equations has no solution that is
a1/a2=b1/b2 is not equal to c1/c2
equations are
2x+3y-1=0
(3k-1)x+(1-2k)y-(2k+3)=0
2/(3k-1)=3/(1-2k)
2(1-2k)=3(3k-1)
2-4k=9k-3
5=13k
k=5/13
