#### MAT-HS.A-REI.01

 MAT-HS Targeted Standards(A) Concept: Algebra(REI) Domain: Reasoning with Equations and InequalitiesCluster: Understand solving equations as a process of reasoning and explain the reasoning MAT-HS.A-REI.01 Explain each step in solving a simple equation as following from the equality of numbers asserted at the previous step, starting from the assumption that the original equation has a solution. Construct a viable argument to justify a solution method.
