Add 3x to both sides
-4y>12+3x
Divide both sides by -4
(-4) -4y>12+3x(-4)
(-4)/-4=1
3/(-4)= 0.75
=
1y>12+0.75x

Answer 1

What my teacher said was wrong~ "Watch your signs"

Answer 2

@abbycross167 on the right side you need dividing every terms by -4 not just 3

Answer 3

the problem is when you multiply or divide by a negative number
you have to "flip" the > to < if you do that

Answer 4

The "safe way" is to add -4y to both sides
–3x –4y > 12
-3x > 4y+12
now add -12 to both sides
-3x-12 > 4y

now you can divide by positive 4 (which is ok)
-¾ x - 3 > y

you can also write that as
y < -¾ x -3
