Question

find the value of k for which the system of equation has unique solution 2 X + 3 Y = K - 1 ,3 x- 5 =2 k + 1​

Answer 1

Answer:

except k = 2/11 all values are possible

Step-by-step explanation:

unique solution = a1/a2 not equal to b1/be not equal c1/c2

2/3 not equal 3/-5 not equal to k-1/2k+1

=3/-5 not equal k-1/2k+1

=6k+3 not equal -5k+5

=6k+5k not equal 5-3

=11k not equal 2

= k not equal 2/11

hope it helps you

Answer 2

Answer:

x=y,6=3k,,

Step-by-step explanation:

2x+3y=k-1,3×-5=2k+1

=2x-3x=k+2k,5+1=3y

=x=y,6=3k
