Question 138352: Solving Systems of Linear Equations by Graphing
2x-y=4
x+y=5
How do I do these equations.
I don't know how to set them up to solve, or what do with them once they are solved. My book does not explain these problems at all.
Thanks

2x-y=4 OR -Y=-2X+4 OR Y=2X-4 (RED LINE)
x+y=5 OR Y=-X+5 (GREEN LINE)
