One Variable Equations and Inequalities

An equation that contains only one variable, such as x, and can be solved to find the value of that variable.

It means that there is no value for the variable that can satisfy the equation.

No Solution

By performing inverse operations to both sides of the equation until the variable is alone.

w = -50

It means to convert a word problem or statement into a mathematical equation that represents the same relationship.

4x + 6 = 30

A mathematical statement that compares two expressions and shows that one is greater than, less than, or not equal to the other.

x = -1

Subtract 5 from both sides to isolate the term with the variable.
