5x + y =22 3x + y= 12 solve by elimination steps

(5, -3)

Step-by-step explanation:

Elimination is also sometimes called 'subtraction' method

Subtract the second equation form the first equation...

  5x + y = 22

-

  3x + y = 12

The result is

 2x = 10        (5x - 3x = 2x, y - y = 0, 22 - 12 = 10)

Now solve for x...

  x = 5          (divide by 2 on both sides)

Now that we know x = 5, plug that into either equation to solve for y...

5(5) + y = 22

  25 + y = 22

        y = -3

II

Step-by-step explanation:

The opinions of viewers of one television station are not necessarily representative of the population of a region.

Say a community has a thousand people, not everyone of those people would watch that exact station, among those that do watch which would be a few percentage, only a few also would even care to participate in the said survey.

You can't take a survey based on the responses gotten on just one station
