  1. Solve Literal Equations for a Specified Variable

  2. What is a literal equation? An Equation with two or more variables. The process of solving a formula for a given variable is called "solving literal equations". One of the dictionary definitions of "literal" is "related to or being comprised of letters", and variables are sometimes referred to as literals. So "solving literal equations" seems to be another way of saying "taking an equation with lots of letters, and solving for one letter in particular."

  3. What is a literal equation? Solving a literal equation differs from solving other equations, because you are not solving for the specific value of a specific variable. You are actually solving for one variable in terms of the other variables. Where a, b, and c are > 0

  4. Solving a literal equation Why do you think we would want to have an equation solved for a particular variable?

  5. What is a literal equation? Literal equations are usually formulas that are used in some type of application such as area, force, volume, or distance. The formula for the area of a rectangle is A = bh We say that this equation is solved for A. Sometimes it may be helpful to solve for a different variable such as b.

  6. Solving a literal equation Solving for a specific variable requires the same skills needed to solve a linear equation. Inverse operations and properties of real numbers are used to isolate specific variables. Division Property Of Equality. Symmetric Property Of Equality.

  7. Properties What properties can be used when solving for a specified variable? Addition Property of Equality Subtraction Property of Equality Multiplication Property of Equality Division Property of Equality Distributive Property Symmetric Property of Equality

  18. Literal Equations Game Pre-game Instructions Break up into groups of two. Each player gets a game card. Each group will cut out their property cards into strips.

  19. Literal Equations Game This game assumes that students have had some practice with solving literal equations. The activity allows students to work with a partner as they identify properties used in solving literal equations. The game also provides examples of solving literal equations so that students can see the steps needed to solve for a variable.

  20. Literal Equations Game Instructions Shuffle the property cards and place them face down in a pile. On your turn, take the top property card and try to place it in the next step of your equation. (If you are just starting, it must be placed on the first step of the equation.) If you can’t use the card, place it face down in the discard pile. The winner is the first person to correctly match a property to each step of all three equations.
