Divide both sides by 3. Examine conditions that the expression in the absolute value is positive and the expression in the absolute value is negative. Treat each condition separately.

|3-6x|=15
3|1-2x|=15
|1-2x|=5

If 1-2x%3C0 Then -%281-2x%29=5
2x-1=5
2x=4
x=2

If 1-2x%3E=0 Then 1-2x=5
1-5=2x
-4=2x
x=-2
