what is h if h/12 + -5 = -17

$$\left({\frac{{\mathtt{h}}}{{\mathtt{12}}}}\right){\mathtt{\,-\,}}{\mathtt{5}} = -{\mathtt{17}}$$

$$\left({\frac{{\mathtt{h}}}{{\mathtt{12}}}}\right){\mathtt{\,-\,}}{\frac{{\mathtt{5}}}{{\mathtt{1}}}} = {\mathtt{\,-\,}}{\frac{{\mathtt{17}}}{{\mathtt{1}}}}$$

$${\frac{{\mathtt{12}}{h}}{{\mathtt{12}}}}{\mathtt{\,-\,}}{\mathtt{60}} = -{\mathtt{204}}$$

$${\mathtt{h}}{\mathtt{\,-\,}}{\mathtt{60}} = -{\mathtt{204}}$$

$${\mathtt{h}} = -{\mathtt{144}}$$
