If 3x = -12 then x must equal -12/3 which is -4
3x + 8 = 20 3x = 20 - 8 3x = 12 3x = 12/3 x = 4
x . 9 =12-3x9x =12-3x9x+3x=1212x =12x =1
3x + 2 = -10 3x = -12 x = -4
6-3x+12=0 6+12-3x=0 18-3x=0 18=3x x=6
12 equals 3x(4) equals 6x(2) equals (12)x1
3x+12 = 18 3x = 18-12 3x = 6 x = 2
3x-4x=12 that means -x equals 12 so x equals -12
3x+12=x+48: 3x-x=-12+48 2x=36 x=18
3x=12 3x/3=12/3 x=4
39
x = 6
2x+12-3x = 5 2x-3x = 5-12 -x = -7 x = 7
6x - 12 = 3x + 15 3x = 27 x = 9
3x+8 = 12 3x = 4 x = 4/3
3x + 8 = 20 3x = 20 - 8 3x = 12 3x = 12/3 x = 4
If: 3x+6 = 12 Then: x = 2
8-3x-x = 12 8-4x = 12 -4x = 12-8 -4x = 4 x = -1
