The value of the inequality equation is x < 22

What is an Inequality Equation?

Inequalities are the mathematical expressions in which both sides are not equal. In inequality, unlike in equations, we compare two values. The equal sign in between is replaced by less than (or less than or equal to), greater than (or greater than or equal to), or not equal to sign.

In an inequality, the two expressions are not necessarily equal which is indicated by the symbols: >, <, ≤ or ≥.

Given data ,

Let the inequality equation be represented as A

Now , the value of A is

x - 8 < 14   be equation (1)

Now , the value of equation can be simplified as

x - 8 < 14

Adding 8 on both sides of the equation , we get

x < ( 14 + 8 )

The value of x < 22

Therefore , the value of x is always less than 22

Hence , the value of the inequality equation is x < 2
