the answer of 3x-4 can be -5 or 5 because of absolute valve.
3x-4=5
3x=9
x=3
3 is the first answer.
3x-4=-5
3x=-1
x=-1/3
second answer is -1/3.

OK.
\[3\left| 2x+4 \right|=12\]\[\left| 2x+4 \right|=4\]
the answer of 2x+4 can be -4 or 4 because of absolute valve.
you should solve these equations to find 2 answers.
2x+4=4
2x+4=-4
