absolute value:

1.|7x+2|=10

x=1.1 x=1.7

2.|3x-5|=-1

x=1.3 x=2

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.

**Chris**, Thursday, August 16, 2012 at 3:14pmSo if the absolute vale equals a negative number there is no solution?

Such as:

|x^2+2x+1|=-4

So, that has no solution?
