\[\boxed{\mathbf{574}.}\]
\[1)\ y = - 5x + 4;\]
\[5x = 4 - y;\]
\[x = \frac{4 - y}{5};\]
\[Ответ:\ \ y = \frac{1}{5}(4 - x).\]
\[2)\ y = \frac{3x - 1}{2};\]
\[2y = 3x - 1;\]
\[3x = 2y + 1;\]
\[x = \frac{2y + 1}{3};\]
\[Ответ:\ \ y = \frac{1}{3}(2x + 1).\]
\[3)\ y = x^{3} - 3;\]
\[x^{3} = y + 3;\]
\[x = \sqrt[3]{y + 3};\]
\[Ответ:\ \ y = \sqrt[3]{x + 3}.\]
