We have -2 from the values in the provided solution set, which is the necessary value.
what is solution set?
A solution set is a group of values in mathematics that satisfy a specified set of equations or inequalities. A constrained optimization problem's viable zone is its solution set of constraints.
Given: - 5x - 15 > 10 + 20x
Let's eliminate the variable x in order to solve the inequality.
5 times both sides,
- 5x - 15 + 5x > 10 + 20x + 5x
- 15 > 10 + 25x
Subtracting 10 from both sides
- 15 - 10 > 10 - 10 + 25x
- 25 > 25x
Dividing both sides by - 25
-1 > x
x < - 1
We have -2 from the values in the provided solution set, which is the necessary value.
