2x + y= 3, 4x + 4y= 8 use substitution to solve the systems of equations

Step-by-step explanation:

y=3-2x

4x+4×3-2x=8

4x-2x=8-12

2x=-4

x=-2

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.
