Solution

1. Find the value of *k* for the given system of linear equations satisfying the condition below:

(i) 2*x* + *ky* = 1; 3*x* − 5*y* = 7 has a unique solution

(ii) *kx *+* *3*y *=* *3; 12*x *+* ky *=* *6* *has no solution

(iii) (*k* − 3)*x* + 3*y* = *k*; *kx* + *ky* = 12 has infinite number of solution

Solution:

2. Find the value of *a* and *b* for which the given system of linear equation has infinite number of solutions 3*x* − (*a* + 1)*y* = 2*b* −1, 5*x* + (1 − 2*a*)*y* = 3*b*
