Algebraic Expressions & Solving Equations Get Ready

Algebraic Expression • A mathematical statement that usually includes one or more variables, constants, and at least one operation (+, – , x , ) but does not include an equals sign (=) • Example: 2 x + 1

Algebraic Equation • An Algebraic expression that has an equals sign and can be solved. You can solve for the value of a variable. • Example: 3 x +6= 12

Variable • A letter used to represent a value that can change or vary • Example: in 4 x – 1, “x” is the variable

Constant • A value that does not change and has no variable attached to it. • Example: in 4 x – 1, “ 1” is the constant

Numerical Coefficient • Is a fixed number that is multiplied to a variable. • Example 2 x – 8 • 2 is the numerical coefficient multiplied to x.

Term • Part of an expression or equation • Formed by the product of numbers & variables that are separated by + & – • Examples: -1, x, 3 y
