Answer 1

Answer:

3x+5y=105

x+y=25

Step-by-step explanation:

x is the number of 3 mile runs so the total distance travelled is 3x miles.  y is the number of 5 mile runs so the total distance travelled is 5y miles.  Together Gavin travelled 103 miles so 3x+5y=105.  

The number of 3 mile and 5 mile runs he did in total were 25 so x+y=25.  

So the answer is:

3x+5y=105

x+y=25

Done.
