In a proportion your numbers increase by the product of the proportion. So if at one point in your graph you had (2,20), the proportion is 10 (2*10=20). Therefore your next points should be 3,30 ;4,40 ; 5,50. Etc.
<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
