Homework Help: algebra

Posted by KC on Saturday, August 18, 2007 at 3:16am.

Solve the system by graphing.

3x+y=6
3x-y=0

I'm kind of unsure about how to do this. I'm thinking I just put any point in for x and then solve for y...is that right?

you could let y=3x then substitute this value of y to the first equation...3x+3x=6 so, evaluating this... you get 6x=6 and your value for x would be 1 and substituting x=1 to y=3x, you get y=3*1
Final answer: x=1 and y=3
