Hi! So i posted a question yesterday and I worked on but before i submit my answer do you think you can check my answers?
1. 7x+3y= pi 4x6y= pi^2
2. 2x+3y= 0 4x+6y= 0 2
3. x+3y=1 4x+ 6y= 1
4. x+y=5 x+2y=10
5. 2x3y=5 4x6y=10
1.U 2.N 3.N 4.U 5.I

If it is a followup question, it is better for you to post the question in the original post, and make a new post to refer to the original post (giving the date and time suffices).
