The temperature on a summer afternoon is 84°f. define a variable and write an expression to find the temperature after it changes. then evaluate your expression for a decrease of 14 degrees fahrenheit.

x - 84 = - 14

Where, x represent the temperature after it changes.

Step-by-step explanation:

Given,

The temperature before changing = 84° F,

Let x be the new temperature after changing,

Thus, the total changes in the temperature = (x - 84)° F,

According to the question,

The temperature is decreased by 14° F,

⇒ x - 84 = - 14

Which is the required expression for finding the temperature after it changes.
