Removal of some of the contents on one of the pages

I have been asked to removes some of the contents on one of the pages due to a copywrite problem. Please tell me how to do that.

Hi George.
Login to your website and in the editor, select the page you want.
Select (highlight) the text and delete by pressing the "Delete"-key. Single words or entire line of text can also be deleted by placing the mouse cursor just after the character you want to delete and press backspace key.

PIC:
Click on the picture you want to delete, and then press DELETE.

Do not forget to click the "Save" button.
