Question 924103
y = round trip distance to office
---
go to office:
time = x
---
return from office:
time = x + 1
s = d/t
20 = (y/2)/(x + 1)
20(x + 1) = (y/2)
40(x + 1) = y
40x + 40 = y
40x - y = -40
---
s = d/t
25 = y/(x + x + 1)
25 = y/(2x + 1)
25(2x + 1) = y
50x + 25 = y
50x - y = -25
---
put the system of linear equations into standard form
---
40x - y = -40
50x - y = -25
---
copy and paste the above standard form linear equations in to this solver:

solution:
x = time to go to office = 1.5 hours
x + 1 = time to return from office = 2.5 hours
2x + 1 = total round trip time to office = 4 hours
y = round trip distance to office = 100 miles
