Alright let's work through this together. First we want to substitute the value given so we are left with only the variable we want to solve for. Hence: $3(-4)-\frac{ 6 }{ x } = 12$

I'll work through pretty quickly just let me know if you don't understand anything. $-12-6/x=12$ (multiply the whole equation by x) $-12x-6=12x$ $24x=-6$ $x=-6/24$ or B when simplified.
