    2(7m-3) = 12m+1
    14m-6 = 12m+1
    2m = 7
    m = 7/2

    Answer: m = 3\frac{1}{2}

    Step-by-step explanation:

    the value of 7m−3 is half as big as the value of 12m+1 implies that

    7m – 3 = \frac{1}{2} ( 12m + 1)

    cross multiplying, we have

    2(7m-3) = 12m + 1

    Expanding the L.H.S , we have

    14m – 6 = 12m + 1

    collecting the like terms ,we have

    14m – 12m = 1 + 6

    2m = 7

    Dividing through by 2

    m = 7/2

    m = 3\frac{1}{2}
