11 liters of 25% orange juice, 4 liters of 10% orange juice:
1' let x to be 25% orange juice and y be 10% orange juice
2' .25x+.10y=(15).21
3' x+y=15
4' 2.5x+y=31.5 divide all sides by 10
5' -x-y=-15 multiply all sides by -1
6' 1.5x=16.5
7' x=11
8' y=15-11=4
so 11 and 4 are the answers.

Answer:
x = a/2 - b/2
y = a/2 + b/2
Step-by-step explanation:
x + y = a
x + b = y
x - y = -b
x + y = a
x - y = -b
________--
2y = a + b
y = a/2 + b/2
x + y = a
x - y = -b
________+
2x = a - b
x = a/2 - b/2
