Joanie believes that you cannot use cross products to solve the proportion 50/3=75/x for x. She says that if you multiply both sides of the equation by x, you get 50x/3=75. Then, if you multiply both sides of the equation by 3, you get 50x=75, which is a different equation than you would get if you cross multiplied. What mistake did Joanie make in her reasoning?

Respuesta :

CastleRook
In the equation 50/3=75/x
multiplying both sides by x we get:
50x/3=75
multiplying both sides by 3 we get
50x=225
this implies that the mistake that Joanie made was that she forgot to multiply 75 by 3.
thus
50x≠75.
