    n=-2

    Step-by-step explanation:

    7/8+n/4=3/8

    n/4=3/8-7/8

    n/4=-4/8

    -4/8=-1/2

    n/4=-1/2

    cross product

    4*-1=2*n

    -4=2n

    n=-4/2

    n=-2

    Step-by-step explanation:

    7/8 + n/4 = 3/8

    Multiply each term by 8

    (8) 7/8 + n/4 (8) = 3/8 (8)

    7 + 2n = 3

    2n = 3 - 7

    2n = - 4

    n = - 4/2

    n = - 2
