### Question:

What is an inequality in algebra?

### Answer:

First, subtract -7 from both sides.

3a≤9

To find, divide each side by 3.

To get,

a≤3

Step 2

This is clear from the following:

Here’s how to write the solution set:

S={a∣a≤3}

Result

S={a∣a≤3}

An inequality in math is a comparison between two numbers or other math expressions that is not equal. On a number line, it is most often used to compare the size of two numbers. An is not the same as b no matter what. These are called “strict inequalities” because an is either strictly less than b or strictly greater than b. Equivalence is excluded.
