A pool is being filled with a large water hose. The height of the water in a pool is determined by 8g^2 + 2g- 3. Previously, the pool had been filled with a different hose.
Then, the height was determined by 5g^2 + 2g - 1. Enter an expression that determines the
height of the water in the pool if both hoses are on at the same time. Simplify the
expression.
An expression that determines the height of the water in the pool if both hoses are on at
the same time is .

Lets see what we're working with here

-18(s) + 24 - [-9] (s) = ?

Take out your "like terms" 
  -9(s) + 36

First,  we have to 'solve' the number -9 which is equal to 0

Solve this one too (only if you want to it to make it easier) (s) - 4 = 0
         We have to add a positive four to your sides (+4)

We have found one solution in this equation

The value of "S" is 4
