Question 162651: Solve by graphing
2x+y=2
-x+y=5
Can you show me, step by step, how this works?

You can put this solution on YOUR website!
First, put the equations in slope-intercept form:
y = -2x + 2
y = x + 5
Then, graph it:
graph%28300%2C200%2C-5%2C5%2C-2%2C8%2C-2x%2B2%2Cx%2B5%29
Now, your answer is the point where they intersect (-1, 4)
