Solve the following equations by using the substitution method;

2x+3y=2
3x-4y=20
 
I worked through the problem on video for you. Feedback on the video is welcomed :). It may take a few minutes to load on dial up.
 
I need hel on these three problems

1. y=2x+1
y=3x-1

2. x=-2/3y
x-4 =-2/5(y+6)

3. 1/2(x-1)+1/39(y+2)=2
1/2x-1/4(y-4)=4


Thanks for helping me on the last problem.
 
What you posted are NOT the answers. You should end with
x=?
y=?
Where ? is a real number. No variables.

New problems should be in a new thread.

With the example of the first, you should be able to at least start on these. Please show your work.
