Problema Solution

The wheel shop has bicycles and go cart bikes has 2 wheels go carts has 4 wheel

S the shop has 21 seats and 54 wheels how many bike and go carts

Answer provided by our tutors

Let


x = the number of bicycles

y = the number of go carts


every bike has 1 seat and every go cart has 1 seat thus


x + y = 21


number of wheel for bicycles + number of wheels for go carts = total number of wheels


2*x + 4*y = 54


Lets solve the system of equations


x + y = 21

2*x + 4*y = 54


we find that


x = 15 bicycles


y = 6 go carts


There are 15 bicycles and 6 go carts in the shop.
