3. Standard
2.0 – Students solve systems of linear equations and inequalities (in two or three variables) by substitution, with graphs, or with matrices.

4. Academic Language System of linear equations Solution of a system
Consistent
Inconsistent
Independent
Dependent

5. System of two linear equations
In two variables x and y, also called linear systems, consists of two equations that can be written in the form
Ax + By = C Equation 1
Dx + Ey = F Equation 2

6. Graph and Find Solution
4x + y = 8
2x - 3y = 18
