Question

for what value of k the equations 3x+2y=6,(k+1)x+4y=2k+2​

Answer 1

Step-by-step explanation:

See answer in above attachment

Answer 2

Answer:

3x+2y=6-----------------(1)

,(k+1)x+4y=2k+2

(k+1)+4y=2(k+1)

(k+1)-(2k+2)=-4y

k+1-2k-2=-4y

-k-1=-4y

k+4y=1------------------(2)

equation (1)has multiple by 2

6x+4y=12---------------(3)

now subscribe of equation (2) and (3)

k+ 4y=1

_6x+_4y=_12

-6kx=-11

k=11/6x
