Step-by-step explanation:
Let x be mixture x liters and y be mixture y liters.
We need a total of 4 liters so
Mixture x is 20% saline solution
Mixture Y is a 10% saline solution
4 liters of a 15% saline solution is 60% saline solution.
So a is the system of equations,
Using Elimination, eliminate the variable x.
Add to the first system.
Plug this into the of system of equations, to find x
So our solution is (2,2) We would need 2 liters of Mixture X and 2 liters of Mixture Y
Are you trying to make x by itself? is this what the equation looks like?
