Ok, we have the equation.

$|x|-4=9$
$|x|=13$

Absolute value means that there will be two solutions.
$x=\pm13$

A

Thats why my name is ISUCKATMATH

austinl · Answer

Absolute value is basically the magnitude of a number, or how far it is from zero.

|13|=13
|-13|=13

Because in each case you are thirteen digits away from the origin.

anonymous · Answer

so since there would be two solutions, then....wouldn't the answer be B?

austinl · Answer

Indeed.
