Solve this system of linear equations. separate the x- and y- values with a comma. 16x-5y=-28 8x-4y=-8

(-3,-4)

Look at attached pictures for work and the text below for the explanation of the work. The brown numbers represent the step number it is.

Step-by-step explanation:

Start by getting either the x or y values in both equations the same number but opposite sign. Ex 16 and -16. I did x. Then add the equations eliminating one variable, in mine it was x, and the solve for the other variable, in mine it was y. Then plug that variable back into one of the two original equations and solve for the other variable, in mine I solved for x.

"it's not the heat, it's the humidity".   that's a partly valid phrase you may have heard in the summer, but it's actually both.   the heat index, also known as the apparent temperature, is what the temperature feels like to the human body when relative humidity is combined with the air temperature.   this has important considerations for the human body's comfort.   when the body gets too hot, it begins to perspire or sweat to cool itself off.   if the perspiration is not able to evaporate, the body cannot regulate its temperature.   evaporation is a cooling process.   when perspiration is evaporated off the body, it effectively reduces the body's temperature.   when the atmospheric moisture content (i.e. relative humidity) is high, the rate of perspiration from the body decreases.   in other words, the human body feels warmer in humid conditions.   the opposite is true when the relative humidity decreases because the rate of perspiration increases.   the body actually feels cooler in arid conditions.   there is direct relationship between the air temperature and relative humidity and the heat index, meaning as the air temperature and relative humidity increase (decrease), the heat index increases (decreases).
