<span>let x be  number of bicycles
 and y the number of</span> tricycles<span>
So 

x + y = 25  equation 1

The number of wheels is
2x + 3y = 63  equation 2 



</span>We can multiply the  equation 1  by two and subtract from the second one...
2x + 3y = 63
-(2x + 2y = 50)
 then  

y = 13 trikes and 
x = 12 bikes
