Let x be the <span>heights of a maple tree and y be the height of the cherry tree.
We know:
</span>

<span>The new ratio is obtained like this:
</span>

.
From the above equation we get

.
then

Solving the above equation for y we get:

So
So the first tree is (400-160=240) more taller than cherry tree.
To solve, you would need to make two equations and substitute one in for the other. Let a = # of adults, and c = # of children
5a + 2c = 1,220
a + c = 295
a + c = 295
-c -c
a = 295 - c
5(295 - c) + 2c = 1,220
1,475 - 5c + 2c = 1,220
1,475 - 3c = 1,220
1,475 - 3c = 1,220
-1,475 -1,475
-3c = -255
-3c/-3 = -255/-3
c = 85
a + c = 295
a + 85 = 295
-85 -85
a = 210
