Question

Find value of k does the pair of equations below has unique solution y-x=6 3kx+2y=7

Answer 1

Answer:

Value of k can be anything other than-2/3.

Step-by-step explanation:

Given System of Equations are

y - x = 6

3kx + 2y = 7

System of equation has unique solution.

To find: value of k

Rewrite in Standard form of equation,

-x + y -6 = 0

3kx + 2y - 7 = 0

So we have following relationship between ratios of their coefficient for the unique solution,

$\frac{a_1}{a_2}\neq\frac{b_1}{b_2}$

$\frac{-1}{3k}\neq\frac{1}{2}$

3k ≠ -2

k ≠ -2/3

Therefore, Value of k can be anything other than-2/3.
