i got a
73 x 3 =219 wheels in tricycle
3 x 2 = 6 wheels in bicycle
for a total of only 225 wheels im short by 2 wheels

Answer 1

i go 75 tricyles x 3 = 225 wheels
1 bike x 2 = 2 2wheels
total of 227 wheels
75 tricyles 1 bicyles

Answer 2

bikes - x
trikes - 76-x

solve:
2x + 3(76-x) = 227
2x + 228 - 3x = 227
-x = -1
x = 1

so 1 bike and 75 trikes

check: 1(2) + 75(3) = 227
