    You could represent this using an algebraic equation such as

    (7 x W) - 8=3 then we could isolate w by adding 8 to both sides and then dividing by 7, which simplifies to W=11/7 or W = 1 4/7

    W = unknown number

    7w - 8 = 3 (product of 7 and a number, w, subtract 8) is 3

    7w = 11

    w = 11/7
