Multiply both sides of the equation by 3.
Subtract 6x on both sides.
Combine 2x and −6x to get −4x.
Add 20 to both sides. Any value plus zero results in its same value.
Divide both sides by −4.
Divide 20 by −4 to get −5.

Answer:
x = 12 hrs to fill the pool
Step-by-step explanation: INCOMPLETE QUESTION
Missed information:
Time for two different sizes hoses to fill a small simming pool (let say that is 3 hours)
Time for one of the two hoses to fill a small simming pool ( lt say that is 4 hours)
With that information we can answer the question
If one of the hoses fill the pool in 4 hours, it will fill 1/4 of the pool in 1 hour
We dont know the other hose how long it take to fill the pool so let call that time x hours then in 1 hour it will fill 1/x of the pool
In 1 Hour the two hoses will fill 1/3 of the pool then
In one hour
1/4 + 1/x = 1/3 Solving for x
( x + 4 )/ 4x = 1/3
3x + 12 = 4x
- x = -12 x = 12 hours
