A. If u have 19 wheels then find the number of bicyćles and tricycles that cañ made.
B. If u have 23 wheels then find the number of bicycles and tricycles can be made ..
"u" is not an English word, however "you" is one.
let the number of bikes be b
let the number of tricycles be t
2b + 3t = 19
integer solutions (b,t) are
(8,1) , (5,3) , (2,5)
for 2b + 3t = 23
integer solutions are:
(10,1) , (7,3) , (4, 5) , (1, 7)
