Answer:
x= 0 and x = -4
Step-by-step explanation:
The first step for absolute value equations is to isolate the expression contained within the absolute value bars:
3|2 x+4|-1 = 11
3|2 x+4| = 12
|2 x+4| = 4
So |2 x+4| is 4 units away from 0 on a number line, but we don't know in which direction -- negative or positive? you'll have two answers.
2 x+4 = 4
AND
2 x+4 = -4
Solve both of those two step equations and you'll get
So 0 and -4 are your solutions
