Question

Find k for unique solution:
3x + 2y = 7 ; 4kx + 2y= 5​

Answer 1

Step-by-step explanation:

3x+2y=7 ----->1

4kx+2y=5 -----'>2

by subtraction above eq we get

3x-4kx=2

(3-4k)x=2

x=2/(3-4k)

from 1--->3(2/(3-4k))+2y=7

by solving above we get

y value

by substituting x and y values in 2 we get k value
