Question 310309: translate the problem into a pair of linear equations in two variables. solve the equations using either elimination or substitution.
In a chemistry class, 5 liters of a 4%-saline solution must be mixed with a 10% solution to get a 6% solution. How many liters of the 10% solution are needed? Answer by Fombitz(32388) (Show Source):
You can put this solution on YOUR website! Let X be the unknown number of liters of 10% solution,
2.5 liters of 10% solution need to be added.
