$1 ) - 5 - 2x = x + 1-2x - x = 1 + 5- 3x = 6\\\\x = 6 / - 3\\\\x = - 2\\\\Comprobamos :\\\\- 5 -2 * - 2 = - 2 + 1\\\\- 5 + 4 = -1\\\\- 1 = - 1\\2 ) 3x + 5.4 = x - 4.6\\\\3x - x = - 4.6 - 5.4\\2x = - 10\\\\x = - 10 / 2\\\\x = - 5\\\\Comprobamos :\\\\3 * - 5 + 5.4 = - 5 - 4.6\\\\- 15 + 5.4 = -9.6\\\\-9.6 = - 9.6 ; 3 ) 2x + 8 = x +2 donde 2x - x = 2 - 8 luego x = -6$
