Question

If ( 2,1 ) is the solution of the linear equation. kx - 2y = 10​

Answer 1

Answer:

2k-2*1=10

2k=12

k=6

Step-by-step explanation:

......…..................

Answer 2

Answer:

put x=2

then. k*2-2y=10

2k-2y=10_1

now put x=1

then k*1-2y=10

k-2y=10_2

solving equation 1 &2

2k-2y=10

k-2y=10

k=0
