Question

5)The value of K for which the 2 points
system of equations x+Ky = 3,
11x-77y = 87has a unique
solution, is
*
O A) K=13
B) K not equl to -7
O C) K=87
OD) k not equal to 0​

Answer 1

Answer: Option B) K≠-7

Step-by-step explanation:

Since the condition for unique solution follows: a1/a2≠b1/b2, if we put the values into the equation,

1/11≠K/-77

Cross multiplying the equation,

11K≠-77

K≠-77/11

K≠-7

Therefore, the correct answer here is Option B) K≠-7
