Question

The temperature in frostburg is -7.This is 18 less than the temperature in coldspot.Find the temperature of coldspot

Answer 1

If the temperature in frostburg is 18 less than the temperature in coldspot, then the following equation compares the two temperatures:

$f = c-18$

where $f,c$ are the temperatures in frostburg and coldspot. Since we're given $f$, we can solve for $c$:

$-7 = c-18 \iff c = -7+18 = 11$
