–7x + 10 = –20 or 10 = 7x – 20

Step-by-step explanation:

Step 1: Subtract 10 from both sides.

−7x+10 −10= −20 -10

−7x=−30

Step 2: Divide both sides by -7.

−7x /−7  =  −30 /−7

x= 30 /7

fahrenheit

step-by-step explanation:

fahrenheit is more precise than celsius. the ambient temperature on most of the inhabited world ranges from -20 degrees fahrenheit to 110 degrees fahrenheit—a 130-degree range. on the celsius scale, that range is from -28.8 degrees to 43.3 degrees—a 72.1-degree range. this means that you can get a more exact measurement of the air temperature using fahrenheit because it uses almost twice the scale.
