General rules for solving equations

• Manipulate the equation until you have a POSITIVE
  variable on one side of the equal sign.
• Whatever you do to one side of the equal sign,
  you MUST do the exact same thing to the other
  side.

3
To Solve

• Determine what is being added to the variable.
• Example

4
Step 1

• Get rid of the 6, so x can be by itself. Do
  the opposite of 6.
• Example

5
Step 2

• Then, what does x equal?
• Example

6
To Solve

• Determine what is being subtracted from the
  variable.
• Example

7
Step 1

• Get rid of the 12, so m can be by itself. Do
  the opposite of 12.
• Example

8
Step 2

• Then, what does m equal?
• Example

9
Things to remember

• Integer rules apply adding and subtracting
  negatives
• Perform the opposite operation, on BOTH sides
  of the equal sign
• Variable must be POSITIVE!
