Solving Multi-Step Equations
Overview
Goal. Solve multi-step equations: simplify each side first (distribute, combine like terms), then undo operations in reverse order, checking by substitution.
Like terms (definition). Terms with the same variable raised to the same power; they can be combined into one term.

Desmos.
1. Type the equation or function you are working with.
2. Read the graph, the table, or the solution Desmos shows.
3. Compare with your own work before you trust it.
TI-84.
1. Press Y= and enter the left and right sides as Y1 and Y2.
2. Press GRAPH to see both sides.
3. Use 2nd TRACE, then intersect or value, to read the key point.
