It is -10 because the symbols r not the same so it is negative
For this case we have the following inequality:
We must rewrite the inequality to find the solution.
By doing distributive property we have:
Adding similar terms we have:
Combining similar terms:
Rewriting we have:
Clearing the value of x we have:
Therefore, the solution set is:
(-∞, 3]
Answer:
The following is not a way to represent the solution of the inequality:
A number line with a closed circle on 3 and shading to the right
