Billy thinks of a nonzero number. He multiplies it by 3. He gets...? 3 options given
[tex]\Large\maltese\underline{\textsf{This problem has been solved!}}[/tex]
This problem does not give us the information about the starting number (we can't read Billy's mind).
First, I'm going to assume that the number is positive
[tex]\bf{A\;positive\;number\;multiplied\;by\;-3;\;yields\;a\;negative}[/tex]
Next, I'll assume that Billy's number is a negative one.
[tex]\bf{The\;number\;is\;a\;positive\;one}[/tex].
[tex]\rule{300}{1.7}[/tex]

[tex]\bf{=The\;answer\;could\;be\;either\;positive\;or\;negative.\;It\;depends\;on\;the\;sign}\\of\:the\:starting\:number.[/tex]
