\[\textbf{а)}\ |x| = 63\]

\[x = 63;x = - 63.\]

\[Ответ:\ - 63;63.\]

\[\textbf{б)}\ |y| = 0\]

\[y = 0.\]

\[Ответ:0.\]

\[\textbf{в)}\ | - y| = 5\]

\[y = - 5;y = 5.\]

\[Ответ:\ - 5;5.\]

\[\textbf{г)} - x = 13\]

\[x = - 13.\]

\[Ответ:\ - 13.\ \]

\[\boxed{\mathbf{1.}}\]

\[- 12 + 4 = - 8\]

\[- 13 + 3 = - 10\]

\[- 4 + ( - 5) = - 9\]

\[- 2 + ( - 3) = - 5\]

\[6 + ( - 6) = 0\]

\[10 + ( - 3) = 7\]

\[\boxed{\mathbf{2.}}\]

\[\textbf{а)}\ 3 + ( - 5) = - 2\]

\[\textbf{б)} - 4 + 5 = 1\]

\[\textbf{в)} - 13 + ( - 4) = - 17\]

\[\textbf{г)} - 2 + 7 = 5\]

\[\textbf{д)} - 3 + 3 = 0\]

\[\textbf{е)}\ 1 + ( - 2) = - 1\]
