let x° be temperature when he woke up. Given that the temperature rose by 11° then later dropped by 14°. Also let $T_b$ be temperature at time she went to bed.

-We add the temperature rise and subtract the temperature drop to find temperature at time she goes to bed.

-The temperature relative to time of waking up can be expressed as:

$T_b=x\textdegree\pm\bigtriangleup T\textdegree\\\\T_b=x\textdegree+11\textdegree-14\textdegree\\\\T_b=(x-3)\textdegree$

Hence, the temperature relative to the time Iko woke up is (x-3)°
