Introduction to Identifying Solutions to an Inequality
Inequality solution is any value of the variable that makes the inequality true.
Solving linear inequalities is almost exactly like solving linear equations.
A solution to an inequality makes that inequality true.
In this lesson, we learn to test if a certain value of a variable makes an inequality true.
Is the following inequality true or false?
x − 6 > 9, x = 14
Solution
Step 1:
Plugging in the value 14 – 6 > 9
8 > 9 which is incorrect.
Step 2:
So, the inequality is False for given value of variable
Is 2 a solution to this inequality?
5x + 14 > 22
Solution
Step 1:
Plugging in the value (5 × 2) + 14 > 22
10 + 14 > 22; 24 > 22 which is correct.
Step 2:
2 is a solution to given inequality.
Therefore, the answer is yes
