Problema Solution
it's a nice spring day in alaska. the temperature in anchorage is -2 times the temperature in nome. the temperature in nome is 6 degrees more than -2 times the temperature in anchorage. what are the temperatures in nome and anchorage?
Answer provided by our tutors
let n = temperature in Nome and a=temperature in Anchorage
We have,
a = -2 * n
so that, n = a/(-2)
n = -2 * a + 6
substituting 'n', we have:
a/(-2) = -2 * a + 6
a = 4a + 6
3a = 6
a = 2
Now solve for 'n':
n = a/(-2) = 2/-2 = -1
The temperature in Anchorage is 2 degrees, the temperature in Nome is then -1 degrees.
