Let $\displaystyle b$ be the number of bicycles
Let $\displaystyle t$ be the number of tricycles

there are 2 pedals per cycle and 50 pedals. obviously, there are 25 cycles. thus:

$\displaystyle b + t = 25$ ........................(1)

there are 64 wheels. each bicycle has 2 wheels, each tricycle has 3, thus:

$\displaystyle 2b + 3t = 64$ ......................(2)

thus, you need to find $\displaystyle t$ from the system:

$\displaystyle b + t = 25$ ........................(1)
$\displaystyle 2b + 3t = 64$ .....................(2)

...why do you h8math?!!
