Making Sure these are right?
absolute value:
1.7x+2=10
x=1.1 x=1.7
2.3x5=1
x=1.3 x=2

1. Eliminate the absoulute value :
7 x + 2 = 10
7 x + 2 =  10
_________________
7 x + 2 = 10
7 x = 10  2 = 8
x = 8 / 7
7 x + 2 =  10
7 x =  10  2 =  12
x =  12 / 7
Solutions x = 8 / 7 aprox. 1.14 and x =  12 / 7 aprox.  1.71
2.Eliminate the absoulute value :
Absolute value can't be negative.
No solutions exist. 
So if the absolute vale equals a negative number there is no solution?
Such as:
x^2+2x+1=4
So, that has no solution?
