Question 923404: A wheel shop sells bicycles and go carts. The bike has only 1 seat and the go cart has only 1 seat. There are a total of 21 seats and 51 wheels in that room. How many bicycles and go carts are in that room? Answer by TimothyLamb(4379) (Show Source):
You can put this solution on YOUR website! b + c = 21
2b + 4c = 51
---
put the system of linear equations into standard form
---
b + c = 21
2b + 4c = 51
---
x + y = 21
2x + 4y = 51
---
copy and paste the above standard form linear equations in to this solver:

answer:
x = number of bikes = 16.5
y = number of carts = 4.5
NOTE: this is a trick question, it's impossible to have fractional bikes or carts
---
solve by substitution:
---
b + c = 21
2b + 4c = 51
---
c = 21 - b
2b + 4(21 - b) = 51
2b + 84 - 4b = 51
2b = 33
b = 16.5 bikes
c = 21 - 16.5 = 4.5 carts
