Outcomes

I.A.REI.1

Explain each step in solving a linear 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. Students will solve exponential equations with logarithms in Secondary Mathematics III.

I.A.REI.3

Solve linear equations and inequalities in one variable.
