Step 1.1

Factor $2$ out of $2 y$ .

$x = - \frac{2 (y) - 2}{y - 1}$

Step 1.2

Factor $2$ out of $- 2$ .

$x = - \frac{2 (y) + 2 (- 1)}{y - 1}$

Step 1.3

Factor $2$ out of $2 (y) + 2 (- 1)$ .

$x = - \frac{2 (y - 1)}{y - 1}$

$x = - \frac{2 (y - 1)}{y - 1}$

Step 2

Cancel the common factor of $y - 1$ .

Step 2.1

Cancel the common factor.

$x = - \frac{2 (y - 1)}{y - 1}$

Step 2.2

Divide $2$ by $1$ .

$x = - 1 \cdot 2$

$x = - 1 \cdot 2$

Step 3

Multiply $- 1$ by $2$ .

$x = - 2$
