Thanks if you can help. =)

1) 4x + 12x + 2/2 =3

8x + 12x + 2 = 6

20 x = 4

x= 4/20= 1/5.
2) 3(x+ 8 ) =12 x

3x + 24 = 12 x

24 = 9x
x = 24/9
= 8/3.

1. X = .2 Steps: 4x + 1/2(12x+2) = 3
4X + 6x +1 = 3
10x + 1 = 3
10x= 2
x =.2

2. X = Steps: 3/2(x + 8) = 6x
3/2x + 3/2*8 = 6x
3/2x + 12 = 6x
1.5x - 6x = -12
-4.5x = -12
x = 2.667

With fractions Multiply the top number by the equation in parentheses.

i.e. 4x + (12x +2)/2 = 3
(3x + 24)/2 = 6x
Then solve the equation as you would any other addition equations containing fractions. From what I gave you you need to find the common denominator then add from there. Hope this helps. Email me if you have more questions at holloway_diana72@yahoo.com.
