You can put this solution on YOUR website!
Want 8 kilograms of mixture, and price to be 174 dollars per kilogram.

Maybe you can do this in one variable.
x=HowMuchKilogramsofPeanut

8-x=HowMuchCashews

Cost%2FMass=Price

highlight%28%28168%2Ax%2B192%2A%288-x%29%29%2F8=174%29
and solving for x should be a mostly simple chore.

You could also do this problem using two variables, like x for peanuts mass and y for cashews mass. You would need one additional kind of equation like x+y=8. The highlighted equation given above would be modified to use the second variable.
