Let's learn how to best select a method to solve equations or inequalities.

**TEKS Standards and Student Expectations**

**A(3)** Linear functions, equations, and inequalities. The student applies the mathematical process standards when using graphs of linear functions, key features, and related transformations to represent in multiple ways and solve, with and without technology, equations, inequalities, and systems of equations. The student is expected to:

**A(3)(D)** graph the solution set of linear inequalities in two variables on the coordinate plane

**A(5)** Linear functions, equations, and inequalities. The student applies the mathematical process standards to solve, with and without technology, linear equations and evaluate the reasonableness of their solutions. The student is expected to:

**A(5)(A)** solve linear equations in one variable, including those for which the application of the distributive property is necessary and for which variables are included on both sides

**A(5)(B)** solve linear inequalities in one variable, including those for which the application of the distributive property is necessary and for which variables are included on both sides

**Resource Objective(s)**

Given an equation or inequality, the student will select a method (algebraically, graphically, or calculator) to solve the equation or inequality.
