Expressions are combinations of variables and numbers, while equations equate two expressions. Variables can take on different values depending on the context, and we can evaluate expressions by substituting values for the variables.

It takes two steps because he first has to subtract 2 from both sides and then multiply both sides by 4. Courses on Khan Academy are always 100% free. Start practicing—and saving your progress—now!
