X=?

please help

Answer 1

Add 4 to both sides
x = 4 + 3 x + 12
combine like terms (4 and 12)
x = 3 x + 16

Answer 2

x-4=3x+12
-12 -12
x-16=3x
-x -x
-16=2x
x=-8

Answer 3

Add 4 to both sides
x = 4 + 3 x + 12
combine like terms (4 and 12)
x = 3 x + 16
subtract 3 x from both sides
- 4 x = 16
divide both sides by - 4
x = -4

Answer 4

Add 4 to both sides
x = 4 + 3 x + 12
combine like terms (4 and 12)
x = 3 x + 16
subtract 3 x from both sides
- 2 x = 16
divide both sides by - 2
x = -8
