Задача 2. Найдите корень уравнения \(-2-3x = 2x + 1\)
Решение
\(-2-3x = 2x + 1\,\,\,\,\,\, \Leftrightarrow \,\,\,\,\,\,-3x-2x = 1 + 2\,\,\,\,\,\, \Leftrightarrow \)
\( \Leftrightarrow \,\,\,\,\,\,-5x = 3\,\,\,\,\,\, \Leftrightarrow \,\,\,\,\,\,x = -\dfrac{3}{5}\,\,\,\,\,\, \Leftrightarrow \,\,\,\,\,\,x = -0,6.\)
Ответ: \(-0,6.\)
