#### Similar standards in other grades

Solve systems of linear equations exactly and approximately (e.g., with graphs), focusing on pairs of linear equations in two variables.

Explain why the ๐น-coordinates of the points where the graphs of the equations ๐บ = ๐ง(๐น) and ๐บ = ๐(๐น) intersect are the solutions of the equation ๐ง(๐น) = ๐(๐น); find the solutions approximately, e.g., using technology to graph the functions, make tables of values, or find successive approximations. Include cases where ๐ง(๐น) and/or ๐(๐น) are linear, polynomial, rational, absolute value, exponential, and logarithmic functions.
