Regroup Terms on One Side

• Subtract right-hand side of each equation from both sides

  • ... thereby regrouping all terms on left-hand side

        My_Spending        - Your_Income                    ≡   0

        My_Financial_Asset - Your_Financial_Liability       ≡   0

        My_Credit          - Your_Debt                      ≡   0

• Rewrite left-hand side as sum of 2 numbers -- one positive, one negative

        My_Spending        + (- Your_Income              )  ≡   0

        My_Financial_Asset + (- Your_Financial_Liability )  ≡   0

        My_Credit          + (- Your_Debt                )  ≡   0

• The terms on left must add up to 0
