A
x=y^2-9
x+9=y^2

2 gallons 25% of 4 is 1 so there is about 1 gallon of pure in there no so adding two will make 3 gallons of antifreeze bringing total to 6 gallons 3/6 = .5 boom bam 50%
2/7=0.28571428571428571428571428571429
0.28571428571428571428571428571429*3=0.85714285714285714285714285714286
that is a long answer but it works
