Question 99443: Hello out there,I need some help with some problems,the first one is,Solve the system of linear equations by graphing:x+2y=5 and x-y=2.The next one is,Solve the system of linear equations by graphing:4x-y=6 and 3x+y=1.The third one is,Solve the system of equations by graphing:y=x^2-4 and y=x-2.And the last one is,Find the solution of the system:y=x^2+5 and y=2x+4.Thanks to whoever can help.

You can put this solution on YOUR website!
I'LL DO THE FIRST ONE & THEN LEAVE THE REST FOR YOU:
X+2Y=5 OR 2Y=-X+5 OR Y=-X/2+2.5 (RED LINE)
X-Y=2 OR -Y=-X+2 OR Y=X-2 (GREEN LINE)
+graph%28+300%2C+200%2C+-6%2C+5%2C+-10%2C+10%2C+y+=+-x%2F2+%2B2.5%2C+y+=+x+-2%29+ (graph 300x200 pixels, x from -6 to 5, y from -10 to 10, of TWO functions y = -x/2 +2.5 and y = x -2).
ANSWER IS (3,1).
