QuestionIdentify the mistake in these steps leading to the conclusion that if $x=1$, then $2=1$.

Studdy Solution
Since we have found the mistake, we do not need to evaluate the remaining conditionals. The mistake lies in the fourth conditional, where division by zero occurs.
The correct statement should be If $(x+2)(x-1)=(x+1)(x-1)$, then $(x+2)=(x+1)$, provided that $x-1 \neq0$. However, since $x=1$, $x-1=0$, and the conditional is undefined.
