HELP ASAP!! PLEASE EXPLAIN! THIS IS Creating Equations and Inequalities of One-Variable

The steps to doing this are as follows:

1. Identify the unknown and represent it with a variable.

2. Set up an equation or inequality using that variable.

3. Solve the equation or inequality to find an answer to the problem.

Explained A one-variable equation is an equation that has exactly one variable in it. Similarly, a one-variable inequality is an inequality that has exactly one variable in it. Setting up one-variable equations and inequalities is an extremely useful tool in mathematics.

in geometry, parallel lines are lines in a plane which do not meet; that is, two lines in a plane that do not intersect or touch each other at any point are said to be parallel. by extension, a line and a plane, or two planes, in three-dimensional euclidean space that do not share a point are said to be parallel.
