Let's bear in mind that 5 gallons with a solution of 6% bleach, contains some water plus some bleach, how much bleach? well, is just 6% of 5 gallons or namely (6/100) * 5 gallons, or 0.30 gallons.
if we use "x" gallons of water, well pure water has no bleach, so is 0% bleach, and it has a (0/100) * x or 0x gallons of bleach.
the mixture will be say "y" gallons, and is 4% bleach, so (4/100) * y is 0.04y gallons in the mixture of bleach.
If n = 5, then 9n = 45
45 - 15 = 30, which is the same thing as 6n
Answer:
x= -2
Step-by-step explanation:
3(x-6) + (4x+12) -6x
3x -18 + -24x - 72
-3x. -3x
-18 = -27x -72
+72. +72
54=-27x
x= -2
