Sorry but I haven't done equations for a few months and these equations are a review to get me ready for the state test and I don't remember how to do them. Below, I have put some equations of two kinds so I'll know how to do them. I'll also put two of the same equations because I really don't get it or forgot.
Equation 1: $${\frac{{\mathtt{2}}}{{\mathtt{3}}}}{\mathtt{\,\times\,}}{\mathtt{x}}{\mathtt{\,-\,}}{\mathtt{1}} = {\frac{{\mathtt{5}}}{{\mathtt{6}}}}$$
$${\frac{{\mathtt{8}}}{{\mathtt{13}}}} = {\mathtt{2}}{n}{\mathtt{\,-\,}}{\frac{{\mathtt{5}}}{{\mathtt{13}}}}$$
Equation 2: $${\frac{{\mathtt{k}}}{{\mathtt{5}}}}$$ ≤ 35
$${\frac{{\mathtt{2}}}{{\mathtt{3}}}}{\mathtt{\,\times\,}}{\mathtt{y}}$$ ≥ $${\frac{{\mathtt{8}}}{{\mathtt{9}}}}$$
