Question

for what value of k the pair of equation 2x+ky=1,3x-5y=7has a unique solution.
​

Answer 1

Answer:

yes, if you put the value of k = -10/ 3.

Step-by-step explanation:

THE GIVEN SYSTEM WILL HAVE A UNIQUE SOLUTION,

a↓1/a↓2 ≠ b↓1/b↓2

2/3≠k/5

-10 ≠ 3k

3k ≠ -10

k = -10/3

so the given system of equation will have a unique solution..
