-------------- percent ---------------- Amount
solution I 73 ---------------- 143 liters
solution II 37 ---------------- x liters
Mixture 51 ---------------- 143 + x liters

73 * 143 + 37 x = 51 ( 143 + x )
10439 + 37 x = 7293 + 51 x
37 x -51 x = -10439 + 7293
-14 x = -3146
/ -14
x = 224.71 liters solution II
