You can use expressions to create equations. ex. 5x+8 is an expression, while 5x+8 = 15 is an equation. Equation: A number sentence that involves operations and numbers and contains an = sign. Both sides of the equal sign must have the same value. Algebraic Equation: A number sentence that contains at least variables, operation, and numbers whereby both sides of the = sign have equivalent values.
