practiceTwo-step equations
An equation says two things are equal. Solving it means finding the value of the variable that makes the statement true. The equals sign is a balance: whatever you do to one side, you do to the other, and it stays true.
How to use it
- Decide what has been done to the variable.
- Undo it, doing the same thing to both sides.
- Keep going until the variable is alone.
Example
Where it goes wrong
- Doing something to one side only.
- Treating the equals sign as "the answer is" rather than "is the same as."
