The problem statement shows that it was copy/pasted into the question rather than typed, so please actually type in an entry.
Let 'x' represent the number of birch, then '2x+4' represents the number of aspens and 'x+50' represents the number of pines.
874=x+(2x+4)+(x+50)
------------------------
------------------------
x=205
2*205+4=414
205+50 = 255
So there are 414 aspens, 205 birch and 255 pines.
