Shanshui flower and bird photography

Solution: Set up a photo exhibition, show X works in total, 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.

Therefore, a total of 160 works were exhibited in this photo exhibition.
