GSE Coordinate Algebra 8-25-15 UNIT QUESTION: Why is it important to be able to solve equations? Standard: MCC9-12.N.Q.1-3, MCC9-12.A.SSE.1, MCC9-12.A.CED.1-4 Today’s Question: How do I use order of operations to solve for a specified value? Standard: MCC9-12.A.CED.4

Standards: MGSE9-12.A.REI.1 Using algebraic properties and the properties of real numbers, justify the steps of a simple, one-solution equation. Students should justify their own steps, or if given two or more steps of an equation, explain the progression from one step to the next using properties. Solve equations and inequalities in one variable MGSE9-12.A.REI.3 Solve linear equations and inequalities in one variable, including equations with coefficients represented by letters. For example, given ax + 3 = 7, solve for x. Solve systems of eqs.

Graph the two equations and find the solution.
