Question 943022: Rachelīs family drove 984 miles in 2 days. If the ratio of the distance covered each day was 20 to 21, find the number of miles they drove each day. Answer by TimothyLamb(4379) (Show Source):
You can put this solution on YOUR website! x = miles driven first day
y = miles driven second day
---
x + y = 984
x/y = 20/21
21x = 20y
---
put the system of linear equations into standard form
---
x + y = 984
21x - 20y = 0
---
copy and paste the above standard form linear equations in to this solver:
