Solving One-Step +/- Equations

Notes for today involved practicing with solving one-step equations using addition and subtraction. Homework is solving 3 word problems which require students to apply writing expressions and solving the equation.  I am requiring students to check their work (insert their solution for the variable) and must always LABEL the solution for a word problem.
