Solve the following equations: x - 2y - 2 = 0 1 - 2y - 2 = 0

The image shows a partial calculation where $x=1$ is substituted into an expression related to the equation $x - 2y = 2$.

Step 1: Identify the equation and substitution. The expression shown is $x - 2y - 2$. If this expression is set to zero, it represents the equation $x - 2y = 2$. The student has substituted $x = 1$ into this expression, resulting in $1 - 2y - 2$.

Step 2: Solve for $y$. We set the expression equal to zero to find the corresponding $y$ value for the line $x - 2y = 2$: $1 - 2y - 2 = 0$ Combine the constant terms: $-1 - 2y = 0$ Add 1 to both sides: $-2y = 1$ Divide by $-2$: $y = \frac{1}{-2}$ $y = -0.5$

The value $y = 0.5$ shown at the top of the image is incorrect for this calculation. The correct value is $y = -0.5$.

The final answer is $\boxed{-0.5}$.
