    C+3D=8

    C=8-3D

    C=4d-6

    8 - 3d = 4d-6

    8+6=4d+3D

    14=7d

    D=2

    Rewrite the second equation in same form as the first So we have

    c + 4d = 8

    c - 4d = - 6 Now add:-

    2c + 0 = 2

    2c = 2

    c = 1

    Now substitute c = 1 in the first equation:-

    1 + 4d = 8

    4d = 7

    d = 7/4 = 1 3/4

    Answer c = 1 and d = 1 3/4 Answer
