Answer 15

.12ofxLiters
.32of y liters

total volume is 8 L

so x+y=8
and
.12x+.32y =
.2 of 8L

we have 2 equations
x+y=8
.12x+.32y =.1.6

make it easier mult 2nd equation by 100
x+y=8
12x+32y =160

lets use the elimination methos mult first equaiotn by 12 and subtract one from the other

12x+12y=96
12x+32y =160

20y=64
y=3.2
y= 3.2L

do the check

and subbing

8-3.2=x
x=4.8L
