Answer 1

Dear student,

$$\begin{gathered} \mathrm{From}\mathrm{the}\mathrm{first}\mathrm{equation} \\ 2\mathrm{x}+6=0 \\ \mathrm{x}=\frac{-6}{2}=-3\mathrm{and}\mathrm{negative}\mathrm{integer} \\ \mathrm{again} \\ 3\mathrm{x}-5=0 \\ 3\mathrm{x}=5 \\ \mathrm{x}=\frac{5}{3}\mathrm{a}\mathrm{fraction} \\ \mathrm{again} \\ 5\mathrm{x}-8=\mathrm{x}+4 \\ 4\mathrm{x}=12 \\ \mathrm{x}=3\mathrm{an}\mathrm{integer} \\ \mathrm{Also} \\ 4\mathrm{x}+7=\mathrm{x}+2 \\ 3\mathrm{x}=-5 \\ \mathrm{x}=\frac{-5}{3}\mathrm{a}\mathrm{fraction}. \end{gathered}$$
