Attached is a front and back cheat sheet for solving and checking equations. These can be used as a teaching tool as well as an instructional support for students with disabilities. Gives step by step instructions on how to solve an equation.

Analyze and solve pairs of simultaneous linear equations.
Solve linear equations with rational number coefficients, including equations whose solutions require expanding expressions using the distributive property and collecting like terms.
Solve linear equations in one variable.
Solve word problems leading to inequalities of the form π±πΉ + π² > π³ or π±πΉ + π² < π³, where π±, π², and π³ are specific rational numbers. Graph the solution set of the inequality and interpret it in the context of the problem. For example: As a salesperson, you are paid \$50 per week plus \$3 per sale. This week you want your pay to be at least \$100. Write an inequality for the number of sales you need to make, and describe the solutions.
Solve word problems leading to equations of the form π±πΉ + π² = π³ and π±(πΉ + π²) = π³, where π±, π², and π³ are specific rational numbers. Solve equations of these forms fluently. Compare an algebraic solution to an arithmetic solution, identifying the sequence of the operations used in each approach. For example, the perimeter of a rectangle is 54 cm. Its length is 6 cm. What is its width?
