MACRO for searching column for a letter and Copy/Paste the row into new MASTER sheet

Can someone please point me in the right direction, I am totally lost.....

I need a MACRO that will search for the letter "x" in a certain column, and if found then copy and paste the row of information associated into a MASTER sheet. The tabs are not named the same but are identical in layout. Search would start at the 8th row of each sheet. This needs to be done for multiple worksheets in the same workbook. I have attached a workbook of what I need.

Note the U004 & U005 are the sheets that I need information from. Going into the master sheet. Wherever there is an "X" in column X, I need that row pasted into Master.

Thanks for the help in advance
