4(4x-3) - 8 = 4 + 3x
4 * 4x = 16x
4 * -3 = -12
Therefore:
16x - 12 - 8 = 4 + 3x
Combine like terms:
-12 - 8 = -20
16x - 20 = 4 + 3x
Subtract 3x from each side of the equation.
16x - 20 - 3x = 4 + 3x - 3x
16x - 3x = 13x
3x - 3x = 0
Therefore:
13x - 20 = 4
Add 20 to each side of the equation.
13x - 20 + 20 = 4 + 20
-20 + 20 = 0
4 + 20 = 24
Therefore:
13x = 24
Divide each side by 13
13x/13 = 24/13
x = 24/13

Answer:
x = 24/13
