both equations are linear and they are not co-linear
therefore there is exactly 1 solutio
Where is the graph. It’s hard to figure out without the info sorry not trying to sound rude.
The first fish has an integer of -4 and the other fish has an integer of -3.
-3 is greater because -4 is one less of -3. If you put it on a line then -3 is closer to the 0 then -4.
So... let's change the concentration percentage to decimal format. .. so 40% is just 4/100 or 0.4 and so on.

so... whatever "x" and "y" may be, we know the must add up to 6 liters.
and whatever 0.4x and 0.8y are, we also know, they must add up to a 3 of concentrated amount.
thus

solve for "x", to see how much of the 40% solution will be needed.
what about "y"? well, y = 6 - x.
