You can put this solution on YOUR website! Let x= amount of white paint to be added
5+x = total amount of white paint
16+x = total amount of paint in the container
Since means that means that gallons of white paint to be added
Check: White paint = 5+17=22 gallons
Total paint = 16+17= 33 gallons. So, 22/33 = 2/3 white paint.

--------------
Equation:
white + white = white
5 + x = (2/3)(x+16)
(1/3)x = (2/3)16 - 5
x = 17 gallons (amt. of white paint needed for the mixture)
