## Answers ( )

Given,Pair of linear equations:

kx–y=2...(1)6x–2y=3...(2)On comparing each linear equations with the standard form of linear equation in two variable (i.e.,), we get

ax+by+c=0a1=k,b1=–1,c1=2a2=6,b2=–2,c2=3ToFind,☛ value of k such that the following pair of linear equations would have a unique solution.

Solution,We know,

for unique solution, the coefficients of two linear equations should follow the following condition.

On solving further,
