Let x = liters 20% solution to be added
then
.12(12) + .20x = .14(12+x)
.12(12) + .20x = .14(12+x)
1.44 + .20x = 1.68 + .14x
.20x = .24 + .14x
.06x = .24
x = 4 liters
Hope this helped!!

Answer: -4x+2
Step-by-step explanation: Simplify
A circle is 360° all the way around; therefore, if you divide anarc's<span> degree measure by 360°, you find the fraction of the circle's circumference that the </span>arc<span> makes up. Then, if you multiply the length all the way around the circle (the circle's circumference) by that fraction, you get the length along the</span>arc<span>.</span>
