8.EE.C.8 - Analyze and solve pairs of simultaneous linear equations.

A. Understand that solutions to a system of two linear equations in two variables correspond to points of intersection of their graphs, because points of intersection satisfy both equations simultaneously.

B. Solve systems of two linear equations with integral coefficients: graphically, numerically using a table, and algebraically by subsititution.

C. Solve real-world and mathematical problems involving systems of two linear equations in two variables with integral coefficients.
