If you are asking if x=0, y=5 is a solution to 5x-3y=15, then no. 0, -5 would be as if you sub in 0 for x you get 5(0) -3y=15, i.e. -3y=15, i.e. y=-5

.05% can be written as .05/100 for Percent is 1/100 of a number.. so .05/100 = .05/100 x 100/100 = 5/10000 or .0005 therefore.. .05% of something is .0005 of something..
05 % = 0.05
Well, it's been awhile since I've done this but my answer would be 24 liters must evaporate to make a 5% solution. 60 * .03 = 1.8 ~ That's what you have. The 1.8 is how many liters of salt you have. 60 = x ~ Replace 60 with x. x * .05 = 1.8 ~ The percentage of salt is now 5 but you still have 1.8 liters. 1.8/.05=36 ~ algebra... 60 - 36 = 24 ~ Total minus how much will remain gives you the total that must evaporate. I know you could have followed them easily enough without the notes. They were more for me so I knew I'd done it correctly. :-) Hope it's right and .
(.05)X(grams of total solution) = grams of acetic acid (grams of acetic acid)/ (mol. wt. of acetic acid(=60g/mol)) = mol. acetic acid (mol. acetic acid)/ (Liters of total solution) = molarity(M)

.05 L x 342 (this is the molecular weight of sucrose) x 1.75 = 29.925g
.05% can be written as .05/100 for Percent is 1/100 of a number.. so .05/100 = .05/100 x 100/100 = 5/10000 or .0005 therefore.. .05% of something is .0005 of something..
optimal solution is the possible solution that we able to do something and feasible solution is the solution in which we can achieve best way of the solution
