Analyze and solve pairs of simultaneous linear equations.

8.EE.C.8.aUnderstand 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.8.EE.C.8.bSolve systems of two linear equations in two variables algebraically, and estimate solutions by graphing the equations. Solve simple cases by inspection.8.EE.C.8.cSolve real-world and mathematical problems leading to two linear equations in two variables.
