Are these right?!
Absolute value :
1. x^22x+16=8
x=4
x=3
x=2
x=2
2.3x2=7
x=5\3
x=3
3. 3x+2+3=0
x= 5/3

1.
x^2  2x + 16 = 8 or x^2  2x + 16 = 8
x^2  2x + 8 = 0 or x^2  2x + 24 = 0
neither the first nor the second has a real solution.
2. 3x2 = 7
3x2=7 or 3x2=7
3x=9 or 3x = 5
x = 3 or x = 5/3
3.
3x+2 = 3
by its very definition, there cannot be a solution here. 
In the first problem it was suppose to be 16
my mistake, but does it still g=have no solution?
