    Hi mafai44,

    Let x = pounds of soybeans needed.
    Let y = pounds of corn needed.

    [1] x + y = 320

    [2] .16x + .08y = .12(320)

    From [1] y = 320 - x

    [2].16x + .08(320 - x) = .12(320)

    16x + 8(320 - x) = 12(320)

    16x + 2560 - 8x = 3840

    8x = 1280

    x = 160 pounds of soybeans needed

    From [1] y = 320 - 160 = 160 pounds of corn needed
