Super urgent, i have a test tomorrow and i need this to be done so i can take it ! 15 pts!
1. y = 3x
4x + 2y =30
2. y = -3x + 6
y = x - 2
3. x - 2y = 3
4x - 8y = 12
4. x - 2y = 3
4x - 8y = 12
show work!

1) y = 3x                                  2) y = -3x+ 6                3) x-2y= 3
4x+ 2y = 30                                 y = x - 2                       4x - 8y = 12

#1) 4x + 6x = 30                      #1) x-2 = -3x+6          0) Unsolvable  
#2) 10x = 30                            #2) 4x  = 8                  
#3) x = 3                                  #3) x = 2                    

4)x -2y=3
4x-8y=12
4) its the same as 3 lol

hope this helps

any questions plz ask in comments below
