Question

Hello I don’t need no explanation or words just the letter thank you so much!Which step has a mistake?

Answer 1

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.
