Answer:

Jada walked
13\ miles

Elena walked
9\ miles

Lin walked
15\ miles

Explanation:

Let

x----> total miles walked by Jada

y----> total miles walked by Elena

z----> total miles walked by Lin

we know that


x+y+z=37 -----> equation A


x=y+4 ----->
y=x-4 ------> equation B


z=x+2 ------> equation C

Substitute equation C and equation B in equation A and solve for x


x+(x-4)+(x+2)=37


3x=37+2


3x=39


x=13\ mi

Find the value of y


y=13-4=9\ mi

Find the value of z


z=13+2=15\ mi

therefore

Jada walked
13\ miles

Elena walked
9\ miles

Lin walked
15\ miles
