Presentation Transcript

  1. 3.1 Two-Step Equations

  2. An equation is like a seesaw. What does that mean?

  3. Your goal is to isolate the variable.

  4. In order to isolate the variable, you must undo whatever is being done.

  5. In order to isolate the variable, you must undo whatever is being done. • Since you are undoing things, they must be done backwards.

  6. DOING UNDOING P E MD AS AS MD E P Remember UNDOINGmeans solving equations

  7. Doing things backwards means reverse the order of operations. 1. Undo any addition or subtraction. 2. Undo any multiplication or division. 3. Undo any exponents.
