Simplify:
![(x)/(z+3)/(x-2)/(x+3)](https://img.qammunity.org/2023/formulas/mathematics/college/5vgj05mwaf0d6fhg7w0jgewtu2rhnn3ywa.png)
Convert the division of fractions into a product with the reciprocal of the denominator:
![(x)/(z+3)*(x+3)/(x-2)](https://img.qammunity.org/2023/formulas/mathematics/college/bpge6aqyw9e4f5t0m7k0juj1nep68h2hn7.png)
Now simplify x + 3 in both the numerator and denominator
![(x)/(x-2)](https://img.qammunity.org/2023/formulas/mathematics/college/nv11pb6w55vzslrzreg69p1lft4z7natyj.png)
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.
