    (x stands for bicycles btw!!)

    2x + 3(93 – x) = 211

    2x + 279 – 3x = 211

    -x = 211 – 279 = -68

    x = -68/-1 = 68.

    68 bikes :))))))

    Answer:

    68 bicycles.

    Step-by-step explanation:

    Let there be x bicycles, then there are (93 – x) tricycles.

    From the given values:

    2x + 3(93 – x) = 211

    2x + 279 – 3x = 211

    -x = 211 – 279 = -68

    x = -68/-1 = 68.
