In maths, Distance is described as the quantity of space between two points, and further calculation can be defined as follows:
Given Expression:
[tex]5x + 2 = 30\\\\2(x + 5) = 30\\\\5(x + 2) = 30\\\\2x + 5 = 30[/tex]
To find:
distance=?
Solution:
[tex]5\ days\ \begin{cases} & \text{ if } \text{before school 2 miles} \\ & \text{ if } \text{after school x miles} \end{cases}[/tex]
[tex]\therefore 5(x+2)=30\\\\[/tex]
[tex]\bold{5(x+2)=30}\\\\\bold{5x+10=30}\\\\\bold{5x=30-10}\\\\\bold{5x=20}\\\\[/tex]
[tex]\bold{x=\frac{20}{4} }\\\\\bold{x=4}[/tex]
Therefore, the final answer is "4 miles".
