    \[\dfrac{1}{3}x - \dfrac{1}{4} = -5\]

    @Hero Typo? You did a - instead of +

    \[\dfrac{1}{3}x + \dfrac{1}{4} = -5\] @lesliee23 Do you know the common denominator?

    Yes, basically one, approach for solving this is to multiply both sides by the common denominator, which, in this case is 12.

    \[(12)\dfrac{1}{3}x + (12)\dfrac{1}{4} = (12)-5\] @lesliee23, What do you think we should do next?

    Okay, so now we have 4x + 3 = (12)(-5). Do you think you could finish it from here?
