Idont know how how to solve linear systems

I do not claim any of this work, I did not do this. I am simply posting this to help a fellow student.

A way to solve a linear system algebraically is to use the substitution method. The substitution method functions by substituting the one y-value with the other. We're going to explain this by using an example.

The solution of the linear system is (1, 6).

You can use the substitution method even if both equations of the linear system are in standard form. Just begin by solving one of the equations for one of its variables.

when the line is solid:

when the line is dashed:

this < inequality sign means:

this > inequality sign means:

this < inequality sign means:
