6 – 7y = 21
бx — 7y = 30
What’s the solution

Step-by-step explanation:

Solving both for 7y gives an equality

6x-30=6-21

6x-30=-15

6x=15

x=5/2 and since 6-7y=21

7y=-15

y=-15/7 so the solution is the point

(5/2,-15/7)

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.
