    Step-by-step explanation:

    The given linear equation is

    4x+7y−10=0

    10x+ky−25=0

    Here a

    1

    =4,b

    1

    =7,c

    1

    =−10

    anda

    2

    =10,b

    2

    =k.c

    2

    =−25

    a

    2

    a

    1

    =

    10

    4

    =

    5

    2

    b

    2

    b

    1

    =

    k

    7

    c

    2

    c

    1

    =

    −25

    −10

    =

    5

    2

    if a linear equation represents a coincident lines then

    a

    2

    a

    1

    =

    b

    2

    b

    1

    =

    c

    2

    c

    1

    Then

    k

    7

    =

    5

    ∴k=
