  1. Step-by-step explanation:

    Have no solution means that the lines are parallel

    i.e.,a1/a2 is equal to b1/b2 is not equal to c1/c2

    In the first equation ,

    2x + 3y = 7 or 2x + 3y -7=0

    a1 = 2 , b1 = 3 , c1 = (-7)

    and in the second equation

    mx +9/2y = 12 or mx +9/2y -12 = 0

    a2 = m b2 = 9/2 and c2 = (-12)

    therefore a1/a2 = 2/m,

    b1/b2 = 3/9/2

    => 3/9 * 2/1

    => 6/9

    => 2/3

    c1/c2 = (-7)/(-12)

    therefore k = 3


    as a1/a2 = b1/b2

    i.e., 2/m = 2/3


    m=3

    I hope that this answer may help u
