Simplify:


(x)/(z+3)/(x-2)/(x+3)

Convert the division of fractions into a product with the reciprocal of the denominator:


(x)/(z+3)*(x+3)/(x-2)

Now simplify x + 3 in both the numerator and denominator


(x)/(x-2)

Steps 3 and 4 are wrong because the variable x disappeared and it cannot be done unless they were simplified or they are substituted by a certain value.
