First you want to isolate X, to do that all you have to do is use the additive inverse and subtract 76 to both sides. the answer you get should be -8.5.

$x=\dfrac{-12}{2}$ and simplified answer : x=-6 i.e. temperature changes by -6 degrees Celsius over a week.

Step-by-step explanation:

Given: The temperature of the city changed by -12 degrees Celsius over a 2 week period.

The temperature changed by the same amount each week.

Let x= average change in temperature

That means , the average change in temperature each week : x = $\dfrac{-12}{2}=-6$

hence, the expression to show the average change in the temperature of the city each week: $x=\dfrac{-12}{2}$ and simplified answer : x=-6 i.e. temperature changes by -6 degrees Celsius over a week.
