Perhaps the easiest way to begin a discussion about algebraic equations and their components is to use examples to point out the various terms. The following expressions will be used to demonstrate the different parts of an equation:

y = 3x − 7 (1.1)

y = 2ax + 3b (1.2)

An equation is a mathematical statement that can be read like a sentence. Equation (1.1) may be read as “y equals 3 times x minus 7.”
