I am working on solving the system of equations by graphing. I am having some problems so I hope someone can show me an easier way of doing this. This is what I have x3y=3 & x+3y=9.

Best ResponseYou've already chosen the best response.0solve each equation for one of the two variables you have as: x3y=3 will be x=3y3. (1) x+3y=9 will be x=9xy (2) find any two points in each function, and connect them with a line. the intersection point is your solution.. I hope that would help

Best ResponseYou've already chosen the best response.0That is were I am running into problems. I think I am getting the first one. Here is what I have so far. 1st equation: x3y=3. I got y=1/3x3/3(1) x=3 and y=1 2nd equation: x+3y=9. I got y=1/3x+9/3(3) x=9 and y=3 The problem I am having is figuring out the second point to draw the line.

Best ResponseYou've already chosen the best response.0well is it okay if we work in my equations.. it looks much simpler. you know how I got them anyway?

Best ResponseYou've already chosen the best response.0hmm I don't think you're following the right method.. you're asked to solve them by graphing.. so find any two points in the line and coonnect them. do this to both lines, just find where they intersect and you're done.

Best ResponseYou've already chosen the best response.0to get points.. just substitute any value for x, get the corespondent value of y.. this is a point

Best ResponseYou've already chosen the best response.0Ok but I never worked i you way. They are showing us theway I put I wrote it. So now I am kind of confused.

Best ResponseYou've already chosen the best response.0I will do your problem the way that's usually done by steps: 1) solve both equations for y: 1st equation: \[y={1 \over 3}x+1\rightarrow (1)\] 2nd equation: \[y={1 \over 3}x+3 \rightarrow(2)\]

Best ResponseYou've already chosen the best response.02) find two points for each equation (intersection points are usually preferred): 1st for equation (1): \[x=0 \implies y=1, x=3 \implies y=2\] so we have the two points in the first line which are (0,1) and (3,2)

Best ResponseYou've already chosen the best response.0for equation (2): \[x=0 \implies y=3, x=3 \implies y=2\] we have two points in the second line, which are (0,3) and (3,2)

Best ResponseYou've already chosen the best response.04) find the point they intersect at (x,y), this point is the solution of the linear system!! :)
