Green car= Red car
2x=x+£50000.
solving this equation by the elimination method we have 2x-x=x-x+£5000
which gives x=£5000
So Blue car costs £5000
Yellow Car costs £5000
Green car costs £10000
Red car costs £10000."
Green car = Red car
2x=x+£50000.
This should be £5000.
Enjoyed the starter though!"
