Answer 1

$\large\boxed{\begin{array}{l}\rm|x-2|\leqslant3\\\rm -3\leqslant x-2\leqslant3\\\rm -3+2\leqslant x\leqslant 3+2\\\rm -1\leqslant x\leqslant5\longrightarrow A\{-1,0,1,2,3,4,5\}\\\rm temos\,7\,soluc_{\!\!,}\tilde oes\,em\,\mathbb{Z}.\\\huge\boxed{\boxed{\boxed{\boxed{\rm\green{\dagger}\red{\maltese}~\blue{alternativa~a}}}}}\end{array}}$
