In the photo exhibition, landscape works accounted for two fifths, and flower and bird works accounted for 1. These two works are * * * 65,438+004, and the rest are works of figures. This time,

Solution: hold a photo exhibition to show X's works, and then:

Landscape works 2/5, flower and bird works 4/X.

Then it is: 5 x+4 x = 104.

Multiply both sides by 20 to get 8x+5x= 104×20.

That is13x =104× 20 =13× 8× 20.

Solution: x=8×20= 160.

So the photo exhibition * * * shows 160 works.
