got any clue how you should solve this ?

nincompoop · Answer

like at least try to come up with something so I know what part you're not getting

miracrown · Answer

First we set up the variables

nincompoop · Answer

I was going to prefer that he exhausts all his knowledge to come up with a solution

dumbsearch2 · Answer

I actually would prefer if @Miracrown could help me come up with a basis for my attempts.

dumbsearch2 · Answer

Shouldn't I do "0.07x + 0.04y = 500" to start off? @Miracrown

nincompoop · Answer

try to "attempt" so we know what knowledge is lacking

miracrown · Answer

LOL- Ok, so Solution are mixed to make 500 milliliters
So X+Y =500. The other equation balances the amount of salt
we have .07 ml of salt in the first solution
.04ml of salt in the second solution
and .05 times 500 ml of salt in the mixture

miracrown · Answer

You can easily solve the system now

nincompoop · Answer

you're missing this part 0.05 (500)

miracrown · Answer

yes and that equaled 25 which I multiplied by 100

dumbsearch2 · Answer
