Question 928936: A petroleum company has two different sources of crude oil. The first source provides crude oil that is 45% hydrocarbons, and the second one provides crude oil that is
95% hydrocarbons. In order to obtain 140 gallons of crude oil that is 55% hydrocarbons, how many gallons of crude oil must be used from each of the two sources?

x + y = 140
45x + 95y = 55*140
---
put the system of linear equations into standard form
---
x + y = 140
45x + 95y = 7700
---
copy and paste the above standard form linear equations in to this solver:
