Now I'm even more confuse, I thought I finally had the answer for the first equation with 45+85=130,52*65=3380/130=26,52-26=26; so 26lbs at 45F and 26lbs at 85F.In your post you said 1040 was specific I don't understand what that means. Did you multiply 26 by 40 to get 1040? Why didn't you do (1040-52*T)/40 in the first equation like you did in the second? I don't understand how you arrive at 4420 for the second equation. When you wrote 45x+85(52-x), does that mean 45 multiplied by x plus 85 multiplied by 52 minus x. Your formula still doesn't show how you went about getting 32.5lbs for 45 and 19.5 for 85. Wouldn't my equation work? If your tired of me then I understand but I cannot let it go until I understand fully. If you reply please try to explain has simply as you can. I give up I think this goes beyond my IQ.

is the formula 45+85= 130 then 52*65=3380/130=26, 52-26 = 26. 85-45=40. Whats the purpose of 40 or 1040?

So if I wanted to get 65F of 52lbs of water do this - 65X52 = 3380 since its two temperature of water do I then do 3380/2=1690/85 = 19.88lbs. 1690/45=37.55lbs. 37.55+19.88= 57.43lbs. It doesn't add up to 52lbs of water, where did I go wrong?

For clarity and for me to get a full understanding please give me an example by using the numbers I posted.

If 45lbs of 45F water plus 7lbs of 85F equals 52lbs and 51F water. How much lbs of 45F and 85F do you need to get 52lbs of 65F water and what is the formula for achieving it?
