Consider the following sequence of algebraic manipulations:$$\begin{aligned}[t]0 \times 2 &= 0 & \text{Line 1} \\ 2 &= \frac{0}{0} & \text{Line 2} && (\text{dividing by } 0) \\ 2 &= \frac{1\times\cancel{0}}{1\times\cancel{0}} & \text{Line 3} && (\text{cancelling common factor}) \\ 2 &= 1 & \text{Line 4} \\ \end{aligned}$$This sequence appears to show that \(2=1\), which is a false result. Identify the line where an invalid mathematical operation is performed.
The error occurs in Line
