Hey Mate..

Substituting x and y ...

We will get .

$k(3) - 3( - 2) = 21 \\ 3k + 6 = 21 \\ k = 5$

Hope it helped ❤️

nazrana32: tx you so much

shrutimohta0220: ur welcome:-):-)

nazrana32: the graph of 2x-3y=6 passes through point_____

nazrana32: plz solved it plz

utkarsh2209: their can be more than one value of x and y

shrutimohta0220: the graph will pass through many points

shrutimohta0220: yes

utkarsh2209: if u take x= 0 and y= -2 then One point can be (0,-2)

Answered by utkarsh2209

here (x,y)=(3,-2)

hence putting this value in kx-3y=21

we get

k(3)-3(-2)=21

3k+6=21

3k=15

hence, k=15/3= 5

k=5 ANS:
