<PRE><B>Question 154544</B>
To solve these:
1) Get everything not in the absolute sign on the right side of the equal sign.
2) Solve the equation.
3) Multiply everything on the right side of the equal sign by -1.
4) Solve that equation.
.
|2x + 6| - 4 = 20
|2x+6|=24
2x+6=24
2x=18
x=9
.
|2x+6|=24
2x+6=-24
2x=-30
x=-15
.
.
6 - 3|2x + 6| = 0
-3|2x+6|=-6
|2x+6|=2
2x+6=2
2x=-4
x=-2
.
|2x+6|=2
2x+6=-2
2x=-8
x=-4
.
.
10 - |x + 2| = 12 
-|x+2|=2
|x+2|=-2
An absolute cannot be negative. There is no answer.
