Given :
The combined height of one for tree and one Pine tree is 21 m.
The height of four for a tree stacked on top of each other is 24 m taller than one Pine tree.
To Find :
How tall are the types of trees that Logan genetically engineered.
Solution :
Let, height of tree and pine tree is x and y.
So, x + y = 21 ...1)
4x - y = 24 ...2)
Putting value of y from equation 1 to equation 2, we get :
4x - ( 21 - x ) = 24
5x = 45
x = 9 m
y = 21 - x = 21 - 9 = 12
y = 12 m
Therefore, length of tree and pine tree is 9 m and 12 m.
