Complete Question:

On Monday, Sarah has to meet her friend at the park after school. The distance from her house to school is 2x + 5. The distance from school to the park is x. If the total distance she walks that day is 10x + 9, how far is it from the park back to her house?

Answer:

$= 7x + 4$

Step-by-step explanation:

Distance from her house to school = 2x + 5

Distance from school to park = x

Total distance walked that day including distance from the park back to her house = 10x + 9

Distance back to her house = total distance walked - (distance form her house to school + distance from school to park)

= $(10x + 9) - ((2x + 5) + (x))$

$= (10x + 9) - (2x + 5 + x)$

$= (10x + 9) - (3x + 5)$

$= 10x + 9 - 3x - 5$

Combine like terms

$= 10x - 3x + 9 - 5$

$= 7x + 4$
