So far, we’ve spent most of our time in this
course simplifying expressions. Today
we’ll begin solving linear equations using a two-column table. The two-column table is based on the idea of using inverse operations to “undo” the operations happening to your variable. When undoing more than one operation, the two-column table will help you perform inverse operations in the right order.
