@bob i dont see what the second equation is.  I dont care for the answer as much as I care for the second equation

First we need to find out 34.5% of 30 liters which is 10.35 liters.The ratios of water to bromine is 4.5:1.So we divide 10.35/5.5=1.88 litersSo we know that bromine is 1.88 liters and water is 8.47 liters.
