I'm answering your question

If anyone can answer I'll become a fan...
OpenStudy (solomonzelman):
I'll show you on a different example, OK?
OpenStudy (solomonzelman):
\[|v | +6= 13 \]\[|v | +6\color{red} {-6}= 13 \color{red} {-6}\]\[|v |=13-6\]\[|v |=7\]by definition, \[|C |=~~C~~~~and~~~-C\]So\[|v |=7~~~or~~~-7\]

That helps... the answer for my question IS NOT A or B, correct?
OpenStudy (solomonzelman):
{a , b} means that either a or b can be the answer.
