Part 2 of 4

Key concepts

3 concepts

  1. 1

    When solving two-step equations, you must 'undo' two operations to get the variable all by itself.

  2. 2

    To solve two-step equations, use the order of operations in reverse, which means you undo addition and subtraction before multiplication and division.

  3. 3

    When an equation has a fraction line, the expressions above and below the line are treated as an 'implied' group, so you undo operations inside the group last.
