You are walking directly away from your house. You were $5$ miles away from your house when you started walking, so you can determine your distance from your house by adding $5$ to the number of miles you have walked. In the table below, $x$ represents the number of miles you have walked, and $y$ represents your distance from home in miles. The relationship between these two variables can be expressed by the following equation: $y=x+5$. Suppose you end up $22$ miles away from home. **How many miles did you walk?** [[☃ input-number 1]] miles $x$ | $y$ :-:|:-: $0$ | $5$ $1$ | $6$ $2$ | $7$ $3$ | $8$
