02.07 Literal Equations
Essential Questions


How can you solve linear equations and inequalities in one variable, including equations
with coefficients represented by letters?
How can you rearrange formulas to highlight a quantity of interest, using the same
reasoning as in solving equations?
In the equation: "distance equals rate times time” ____________________ is the most important
part. d=(r)(t)
In d=(r)(t) the more efficient way to evaluate r is to__________________ it from the rest of the
equation first.
Work ______________________ to isolate the variable.
The key to equations is ________________________.
Some literal equations (formulas) have several variables. In order to solve for a certain variable, you
must consider the ______________________of the variable you are solving for and
“________________” what is around it.
When the entire equation is made up of variable you will need to
____________________________________ to solve for the desired variable.
Area of a Rectangle = Length • Width
A = L • W To get W on one side by itself, you
need to get rid of____. W is being multiplied to ____ so do the _________________ and divide
both sides by ___.
Try it! Solve for W:
A=L•W
Work Space:
A rectangular bedroom has a length of 14 ft. If the area of the room is 126 ft2, what is its width?
Now, you can ______________________the values you were given for A and L to find W!
W= ___
Solving literal equations and inequalities is exactly the same as
_______________________________________
____________________________________.

Determine which variable needs to be ______________________.
Highlight the variable and determine what __________________ are being applied to
that variable.
_____________________________________to isolate the variable.
When multiplying or dividing by a negative number, be sure to
