Answer:

Equations and inequalities are both mathematical sentences formed by relating two expressions to each other. In an equation, the two expressions are deemed equal which is shown by the symbol =.

x=y

x is equal to y

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

x>y

x is greater than y

x≥y

x is greater than or equal to y

x<y

x is less than y

x≤y

x is less than or equal to y

An equation or an inequality that contains at least one variable is called an open sentence.

When you substitute a number for the variable in an open sentence, the resulting statement is either true or false. If the statement is true, the number is a solution to the equation or inequality.

Example

Is 3 a solution to this equation?

5x+14=24

Substitute 3 for x

5⋅3+14

5+14=29≠24

FALSE!

Since 29 is not equal to 24, 3 is not a solution to the equation.
