A.4
The student will solve multistep linear and quadratic equations in two variables, including
a)   solving literal equations (formulas) for a given variable;
b)   justifying steps used in simplifying expressions and solving equations, using field properties and axioms of equality that are valid for the set of real numbers and its subsets;
c)   solving quadratic equations algebraically and graphically;
d)   solving multistep linear equations algebraically and graphically;
e)   solving systems of two linear equations in two variables algebraically and graphically; and
f)   solving real-world problems involving equations and systems of equations.
Graphing calculators will be used both as a primary tool in solving problems and to verify algebraic solutions.
