For problems 1 and 2 write Y as a function of X
1) 12=9x+3y
- I think you would subtract 9 from the 12.. but I'm not really sure because you can't add/subtract x's and y's from regular numbers.
2) -2x+3y=9
Same problem as above..
Can someone please explain to me how to do these problems?!
Thank you.
