Question

If (2k-1,k) is a solution of the equation 10x-9y=12 then k =

Answer 1

Answer:

k=2

Step-by-step explanation:

11k=22

k=22/11

k=2

Answer 2

Answer:

Let X be 2 k -1 and Y be k

Given

10x-9y=12

So

10(2k-1)-9(k)=12

20k-20-9k=12

20k-9k-20=12

11k-20=12

11k=12-20

11k=-8

k=-8/11

or

k=0.7272
