Inverse Operations
­­ operations that undo each other
Equivalent Equations
­­ equations that have the same solution
You can, add or subtract, multiply or divide, the same number from each side of an equation to form an equivalent equation.
*** The goal in solving an equation is to get the variable alone on one side of the equal sign.
*** To solve an equation, you "undo"
what is happening to the variable.
In other words you use the inverse
operation.
*** To keep an equation balanced,
you must do the same thing to both
sides of the equation.
