Overview

Simple linear equations are statements in which two expressions are equal and one unknown value is found by solving. The variable is usually x, y, or z. A solution is the value of the variable that makes the equation true. Solving an equation means finding that value by keeping both sides equal whil

Key Concepts

An equation is a statement

An equation is a statement which states that the two expressions are equal. For example, 3x + 2 = x - 7 is an equation because both sides have the sam

A variable is the unknown quantity

A variable is the unknown quantity in an equation whose value is found by solving. Common variables are x, y, and z.

The solution is the value

The solution is the value of the variable that satisfies the equation. For example, x + 2 = 6 has solution x = 4.

An equation remains unchanged if

An equation remains unchanged if the same number is added to each side, subtracted from each side, multiplied on each side, or if each side is divided

In transposition

In transposition, a term moves from one side of the equation to the other and its sign or operation changes. A positive term becomes negative, a negat
