What is a literal equation?
A literal equation is an equation
that contains more than one
variable.
When you solve a literal equation,
you are rearranging the equation
to isolate a variable.

Solve ax + b = c for x
 Solve the equation ab + cd = g for c
 Solve the equation ab + cd = g for a.
1) Solve 3x - 6y = 17 for x.
To get x by itself, what is the first step?
1. Add 3x
2. Subtract 3x
3. Add 6y
4. Subtract 6y
1) Solve 3x - 6y = 17 for y.

You Try!
1. P= IRT
for T
2. A= 2(L + W)
for W

3. y= 5x - 6 for x
4. 2x +3y = 8 for y
9z + 2a = 3j – 4x
