Delete cells based on Prefix

I have a macro that currently deletes blank rows in column A and then a few unnecessary columns E and G. The report has changed on me and now in column E I must delete all the locations that begin with "MX " and there is just too many to be selecting one by one. Is there anything I can add to this current macro to delete all Locations that begin with "MX "? there are many other prefixes such as "US" "CA" but the one I need to delete are "MX" the whole row where the MX is found in column E needs to be deleted...

Sub Delete()

    Dim cRow As Long
    cRow = 3
    Do While (IsEmpty(Cells(cRow, 1)))
    cRow = cRow + 1
    Loop
    cRow = cRow - 1

    Columns("E:E").Select
    Selection.Delete Shift:=xlToLeft
    Columns("G:G").Select
    Selection.Delete Shift:=xlToLeft

    if range("E" & cRow).value like "MX*" then 'OR left(range("E" & cRow).value, 2) = "MX"
       Rows("3:" & cRow).Delete Shift:=xlUp

    end if 

End Sub
