When solving two step equations, the goal is always to isolate the variable.
In this process, there are a few rules to follow: 1) Distributive Property and combining like terms if necessary. 2) Use inverse operations of addition or subtraction (for variables and constants). This step will get rid of the variable on one side of the equation and we will now see an equation we're used to working with. 3) Use inverse operations of multiplication or division. Note: If an inequality sign is present, multiplying or dividing by a negative value will flip the inequality sign. When asked to write an algebraic equation from a verbal description, I have found that these steps are helpful for my students: 1) Rewrite numbers, 2) Identify the variable, and 3) Use keywords for operations |
