Answer: w=-6/14
Step-by-step explanation:
First you are going to put one equation on top of the other and subtract. Then you will use your new equation to combing like terms then divide your end result by your w value and make an improper fraction.
Given:
The inequalities are:
or ![2x](https://tex.z-dn.net/?f=2x%3C-8)
To find:
The solution for the given inequalities and graph the solution.
Solution:
We have,
or ![2x](https://tex.z-dn.net/?f=2x%3C-8)
Solve the above inequalities separately.
![-5x](https://tex.z-dn.net/?f=-5x%3C-3)
Divide both sides by -5.
![x>\dfrac{-3}{-5}](https://tex.z-dn.net/?f=x%3E%5Cdfrac%7B-3%7D%7B-5%7D)
...(i)
And,
![2x](https://tex.z-dn.net/?f=2x%3C-8)
Divide both sides by 2.
![x](https://tex.z-dn.net/?f=x%3C%5Cdfrac%7B-8%7D%7B2%7D)
...(ii)
From (i) and (ii). we get
or ![x>\dfrac{3}{5}](https://tex.z-dn.net/?f=x%3E%5Cdfrac%7B3%7D%7B5%7D)
The interval notation of the solution is
.
The graph of the solution is shown below.
