 * 1) $$ \vert x \vert = 7. $$
 * 2) $$ \vert x + 2 \vert = 7. $$
 * 3) $$ \vert 2x - 3 \vert = -2. $$
 * 4) $$ \vert x - 3 \vert = 0. $$
 * 5) $$ \vert x - 3 \vert = \vert x \vert. $$
 * 6) $$ \vert 2x + 3 \vert = x. $$
 * 7) $$ \vert 1 + x \vert = \vert 1 - x \vert. $$
 * 8) $$ \vert 1 + x \vert = \vert 1 - 2x \vert. $$
