Question

for what value of k the following system of linear equation have unique solution 2 X + K is equals to 1 and 3 x minus 5 Y = 7 for what values of K the pair of linear equation 3 x minus 5 equals to 16 - k y = 2 have unique solution

Answer 1

Answer:

k=-5/7 or -10/3

Step-by-step explanation:

2x + k = 1

3x - 5y = 7

a1/a2 = b1/b2 =c1/c2

2/3 = k/-5 = 1/7

k/-5 = 1/7

k = -5/7

or

k/-5 = 2/3

k = -10/3
