SOLUTION: I have to graph this 2x+3y=34 and 25x+30y=350 as well as work it out. All I got out of this was y=-5/6x+35/3 and if that is right for the 2nd equation I don't know how to graph it

Question 301188: I have to graph this 2x+3y=34 and 25x+30y=350 as well as work it out. All I got out of this was y=-5/6x+35/3 and if that is right for the 2nd equation I don't know how to graph it and 34/3 and -2/3 for the first equation and if thats right I don't know how to graph it. Please help me I need this done in a couple days. I appreciate all of your help and support.

You can put this solution on YOUR website!
2x+3y=34
25x+30y=350
multiply the first by -10
-20x-30y=-340
add
5x=10
x=2
2*2+3y=34
3y=30
y=10
x=2 y=10

I have to graph this
2x+3y=34
---
y = -(2/3)x + (34/3)
Plot two points and draw a line thru them:
If x = 0, y = (34/3) = 11 1/3 giving you point (0,11 1/3)
---
If x = 3, y = -2 + 34/3 = 28/3 = 7 1/3 givng you point (3, 7 1/3)

25x+30y=350
---
y = (-5/6)x + (35/3)
Plot two points and draw a line thru them.
If x = 0, y = (35/3) = 11 2/3 giving you point (0, 11 2/3)
---
If x = 6, y = -5 + 35/3 giving you point (6, 6 2/3)
