SWBAT solve for a variable in a literal equation.
Literal Equations Just a whole bunch of letters!
Literal Equations An equation comprised only of variables! That means it is all letters!!! Only variables?! What does that mean?
Literal Equations Literal equations is the fancy word for formula A formula is an algebraic expression relating two or more quantities For example: The formula for area of a rectangle is A = bh The formula for the volume of a prism is V = Bh The formula for distance is d = rt
The Goal of Literal Equations Isolate (solve for) a particular variable This means that you must get everything on the right side of the equal sign except the variable you are solving for
Key Point: By definition, variables represent numbers. Therefore (and this KEY), variables have the same properties as numbers …
Variables can cancel each other out. I think that is called inverse operations, right? Can we review those?
To cancel variable … You must do the inverse (opposite) operation
So here we go … You guys are practicing? Huh, interesting. Perhaps I should try that. Because I don’t think that we have a team that will the west this year!
