MA.8.AR.2.1 · Algebraic Reasoning
Multi-step linear equations are the core 8th grade algebra skill: distribute, combine like terms, collect variables on one side, and solve. Students also classify equations that finish with one solution, no solution, or infinitely many solutions.
FAST items lean on the equation editor for the value of the variable, with multiple choice items for the solution-count question. When both sides simplify to the same statement the answer is infinitely many, and when they contradict, as in 0 = 3, there is no solution.
These come straight from Algebro's 8th grade pre-algebra question bank, easiest first. Answer one, check it, then move to the next.
