Key concepts
3 concepts
- 1
To solve an equation, you must rearrange it so the unknown value is by itself on one side of the equal sign.
- 2
An equation is like a balance scale, so any operation performed on one side must also be performed on the other side to keep the equation balanced.
- 3
To isolate an unknown value, use the inverse operation; for example, use subtraction to undo addition.
