Question 972683
x=how much of 6%
833-x= how much of 23%

833*.14= .06x + .23(833-x)  units here are liters-salt
116.62=.06x + 191.59-.23x
subtract 191.59 from both sides

-74.97=-.17x

divide both sides by -0.17
441 liters of 6%  or 26.46 liters-salt
392 liters of 23% or 90.16
Sum is 833 liters of .14  = 116.62

The answer is 441 liters of the 6% solution
