Question

for which value of k will the following pair of linear equation of solution 3 X + Y equal to 1 and 2 k - 1 into X + K - 1 into Y equal to 2 k + 1​

Answer 1

Answer:

hey buddyy

howz uhh...???

given,

3x + y = 1

=> 3x+y-1=0

(2k-1)x + (k-1)y = 2k+1

=> (2k-1)x+(k-1)y-2k-1 =0

We know,

a1/a2 = b1/b2 not equal to c1/c2 has no solution

Now, we have,

a1=3 , b1=1

a2=2k-1 , b2 = k-1

3/2k-1 = 1/k-1

3(k-1) = 2k -1

3k-3 = 2k -1

3k -2k = -1 +3

k = 2

I hope it will help uhh....
