|2x+8|=3x+7
[2X + 8] = 3X + 7,
The absolute value of a number is always positive, but the number it self could be negative:
+-(2X + 8) = 3X + 7,
Using the positive value:
2x + 8 = 3x + 7,
2x - 3x = 7-8,
-x = -1,
x = 1,
Use the negative value:
-(2x + 8 = 3x + 7,
-2x - 8 = 3x + 7,
-2x -3x = 7 + 8,
-5x = 15,
x = -3.
Solution set: x = 1; x = -3.
