okay so for these one it be |3x-2| = |2x+5| because 1 times in with |2x+5| or it be (-2x-5)

**Steve**, Thursday, January 19, 2012 at 10:12amif 3x-2 > 0 then |3x-2| = 3x-2

if 2x+5 > 0 then |2x+5| = 2x+5

in this case,

3x-2 = 2x+5 + 1

x = 8

since 8 satisfies the conditions, it is a solution

if 3x-2 < 0 then |3x-2| = -(3x-2)

if 2x+5 > 0 then |2x+5| = 2x+5

in this case,

-(3x-2) = 2x+5 + 1

x = -4/5

since -4/5 satisfies the conditions, it is a solution

If you work through the other two choices, you will either find no more solutions, or duplicates of these.
