The solution to the given inequality is x > -5.
{x| x is all real numbers from -5 to infinity excluding -5 its self.}
( -5, ∞ )
<h3>What is the solution to the given inequality?</h3>
Given the data in the question;
First, we solve for the x in the given inequality.
-9 - 6x < 21
Collect and add like terms
-6x < 21 + 9
-6x < 30
Divide both side by -6.
Note that; when dividing or multiplying both sides by a negative value, the direction of the inequality sign flips to the other side.
-6x/-6 > 30/-6
x > -5
x:| x is all real numbers from -5 to infinity excluding -5 its self.
( -5, ∞ ).
