Temperature in Cold-spot is ${11}^{\circ} C$

#### Explanation:

Let $f$ be the temperature in Frost-burg and $c$ be the temperature in Cold-spot (both in degrees centigrade).

We are told
[1]$\textcolor{w h i t e}{\text{XXX}} f = - 7$
and
[2]$\textcolor{w h i t e}{\text{XXX}} f = c - 18$

Substituting the value $\left(- 7\right)$ (from [1]) for $f$ in [2]
[3]$\textcolor{w h i t e}{\text{XXX}} - 7 = c - 18$

Add $18$ to both sides:
[4]$\textcolor{w h i t e}{\text{XXX}} 11 = c$
