For this case we must resolve each of the inequalities and find the solution set.
Inequality 1:
We subtract 7 from both sides of the inequality:
We divide between 12 on both sides of the inequality:
Thus, the solution is given by all values of x less than
Inequality 2:
We add 8 to both sides of the inequality:
We divide between 5 on both sides of the inequality:
Thus, the solution is given by all values of x greater than
The solution set is given by:
(-∞, ) U (
,∞)
Answer:
(-∞, ) U (
,∞)
