Tips for Solving Literal & Other Equations:
1. If the variable you are solving for is inside the
parenthesis, you must distribute first. 9p = 3(k + 5) for k
2. If the variable you are solving for is outside the
parenthesis, simply perform the opposite operation.
9p = 3k(p + 5) for k
3. When clearing fractions, if the denominator being
multiplied has two or more terms, it must be distributed on
the other side.
5k( 2p + 4) = 9

4. Always check to see if every term has something in
common. You can then factor it out.
3kp – 7km – 9k – 1 = -7p + 10 for k
first
3kp – 7km – 9k = -7p + 11
Then,
k(3p – 7m – 9) = -7p + 11 Then What?
k= -7p + 11
(3p – 7m – 9)

Tips for Solving Literal & Other Equations:
5. If an entire term can be factored out, replace it
inside the parenthesis with a ‘1’
2p + 8px = ?
2p(1 + 4x) check by distributing the 2p again.
6. When solving fractional equations, you may have to
clear fractions more than once.

7. Two equal fractions is called a proportion.
Proportions can be solved by cross multiplying.
The following is not a proportion.
