_____
An absolute value is zero only when its argument is zero. The linear expression that is the argument will be zero for only one value of x: -3.

Answer:
One solution
Step-by-step explanation:
Based on a property of a Modular Function. If |x| =0 then x=0
|4x +12|=0
4x+12=0
4x+12-12=-12
4x=-12 *1/4
x=-3 S={-3}
Check the graph below to see the point (-3,0) i.e. x=-3 as the only solution that satisfy the equation
