A chemical company makes two brands of antifreeze. The first brand is 55% pure antifreeze, and the second brand is 75% pure antifreeze. In order to obtain 60 gallons of a mixture that contains 60% pure antifreeze, how many gallons of each brand of antifreeze must be used

set each factor equal to 0

4x-3 = 0

2x-1 = 0

solve for x.

4x-3=0

4x=3

x= 3/4

solve for x. 

2x-1= 0

2x= 1

x= 1/2

eventually after a few more steps, your answer should be 1/2 is less than or equal to x and 3/4 is greater than or equal to x
