3x-6+4=-20
- add 6 to both sides
3x+4=-20 +6
3x+4=-14
- then subtract 4 from both sides
3x=-14 - 4
3x=-18
- then divide 3 from both sides
-18 divided by 3 = -6
x= -6
3x-6+4=-20. First, you would take -6 and add 4 which would give you -2. So now the equation is, 3x-2=-20. then you would take -20 and move -2 over and add it because you would do the inverse. Then you have 3x=-18. So then you would take -18 and you will do 3x and divide it because you would do the opposite of multiplication. so then you would get x=6
