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.
