    There are 4 bicycles there.

    Step-by-step explanation:

    29:

    we will think of a number to include the tricycles and the bikes so, we will divide the 29 into "21 and 4"

    4 = 8÷2 (Because bicycles had 2 wheels)

    7 = 21 ÷ 3 (Because tricycles had 3 wheels)

    11 riders = 4+7

    Therefore there are 4 bicycles there.

    4 bicycles (2 wheels)

    7 tricycles (3 wheels)

    = 11 riders

    4 bicycles

    Step-by-step explanation:

    It is very hard to explain, but I'll try. These were never included in our lessons, so I might explain in a different way than the formula you were thought to do.

    Find the digits that make up 29 that is divisible by 3 and 2

    Ex.: 21+8, 21 is divisible by 3 and 8 is divisible by 2

    21 ÷ 3 = 7 tricycles (and also 7 riders)

    8 ÷ 2 = 4 bicycles (also 4 riders)

    7 tricycles x 3 wheels = 21 wheels

    4 bicycles x 2 wheels = 8 wheels

    21 + 8 = 29 wheels

    7 + 4 = 11 riders( since each vehicle has 1 rider)

    7×3=21

    4×2=8

    21+8=29

    so there are 4 bicycles

    There are 4 Bicycles /2 wheels

    7 tricycles /3 wheels

    = 11 riders

    Bicycle = 2 wheels
    tricycle = 3 wheels
    Let x be the number of bicycles and
    y be the number of tricycles.

    2x + 3y = 29
    x + y = 11 => x = 11 - y

    2x + 3y = 29
    2(11 - y) + 3y = 29
    22 - 2y + 3y = 29
    y = 29 - 22
    y = 7

    x + y = 11
    x + 7 = 11
    x = 11 - 7
    x = 4

    There are 4 bicycles and 7 tricycles.

    Check:
    2x + 3y = 29
    2(4) + 3(7) = 29
    8 + 21 = 29
    29 = 29 ✔
