    -\left(\frac{12}{-3}\right) + 5 \cdot (2) = -(-4) + 10 = 4 + 10 = 14

    Could it be that the original question reads:

    -\left(\frac{12}{-3}\right) + 5 \cdot (-2) = -(-4) - 10 = 4 - 10 = -6

    Of course, that is possible too. But there are some more possibilities, for instance:

    -\left(\frac{12}{-3} +5(2)\right) = -(-4+10) = -6
