Answer 2

Answer: The height of each fir tree is 9 meters, and the height of each pine tree is 12 meters.

Explanation:

Let x= height of each fir tree, y = height of each pine tree.

As per given, we have

x+y = 21 (i)

4x=y+24 (ii)

From (ii),

`4x-y=24` (iii)

Add (i) and (iii), we get

`5x=45\\\\\Rightarrow\ x=(45)/(5)\\\\\Rightarrow\ x=9`

Put value of x in (i), we get

`9+y=21\Rightarrow y=12`

Hence, the height of each fir tree is 9 meters, and the height of each pine tree is 12 meters.
