The equation $5x + 10 = 10y$ is a linear equation in two variables, $x$ and $y$. Let's solve for $y$ in terms of $x$.

Steps:

1. Subtract 10 from both sides to isolate the term with $y$ on the right side: $5x = 10y - 10$

2. Rearrange the equation by adding 10 to both sides: $5x = 10y$

3. Divide both sides by 10 to solve for $y$: $y = \frac{5x}{10} = \frac{x}{2}$

Thus, the equation in terms of $y$ is: $y = \frac{x}{2}$

This equation represents a line with slope $\frac{1}{2}$ and a y-intercept of 0.
