The goal with the sheets below is to practice solving for variables by applying the subtraction principle in order to balance algebraic expressions. Some of the problems require the conversion of a fraction first. There are a number of problems in here that require you to do more than just find the difference between two items to fully solve it.
These worksheets demonstrate how to find the value of a variable by manipulating the known numbers in the equation. Also included are practice worksheets, review sheets, and quizzes to help master the skill.
