Question 301746: 6x+y=44
6x+7y=28
I do it this way correct:
6x+7y(44-6x)=28
6x=308-42x=28
48x+308=28
co efficient is 48
48x+308=28
48x-336
x=7
y=44 -6(7x)
44-42
y = 2

Question 304360: I have to figure out how much no fat yogurt should be mixed with regular yogurt to obtain 60 pounds of low fat yogurt.
I have 3% fat yogurt blends with no-fat yogurt that yields a 1%low fat yogurt.
I know that x60 is what I need to determine.
.03x is the 3%, .01 is the 1% which gives me 4% total lowfat yogurt. Then I divided that into the 60 needed and I came up with 17 pounds.
