Substitute for x+2y=12 and x=y-12

PLEASE HELP !

x = -4, y = 8

Step-by-step explanation:

y - 12 + 2y = 12

=> 3y = 24

=> y = 8

x = 8 - 12

=> x = -4

x = -4

y = 8

Step-by-step explanation:

We can substitute:

=> (y - 12) + 2y = 12

=> 3y - 12 = 12

=> 3y = 12 + 12

=> 3y = 24

=> y = 24/3

=> y = 8

Now we can substitute 8 in for y, in any of the equation given to find x:

=> x = (8) - 12

=> x = -4

Hope this helps!

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.
