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

Please show work!

Answer 1

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
