Question

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 ..

Answer 1

"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)
