Answer:
As the height increases, the temperature decreases.
It is decreasing 5°C per kilometer.
At the height 8 km the temperature is 0°.
8x + 6 - 2x = 34x
Simplify 8x +6 - 2x to 6x + 6:
6x + 6 = 34x
Subtract 6x from both sides:
6 = 34x- 6x
Simplify 34x - 6x to 28x:
6 = 28x
Divide both sides by 28:

= x
Simplify

to

:

= x
Now switch sides and the answer is:
x =
