    Answer:

    x – 18°F = 2°F

    x = 20°F

    Step-by-step explanation:

    First, write the equation with the information you know. It dropped 18°F from 6 to midnight, and by midnight the temperature was 2°F

    Your equation should look like this: x – 18°F = 2°F

    Move the constant to the right hand side and change it’s sign:

    x = 2°F + 18°F

    Add the numbers to get x = 20°F

    Hope this helped!
