Given the system of linear equations. Choose all of the options that could be used to solve the system using addition

myrzilka [38]

<h2>Hello!</h2>

The answer is:

The only operations that could be used to solve the system using addition are the first and the third operation.

To solve the problem, we need to check and discard each of the given option to see if the operations works to solve the system using addition, so, trying the given options.

The system of equation is:

$x+y=7\\12x+y=5$

We can see that the only way to solve the system using addition, is multiplying the first or the second equation by -1, so, we can eliminate the variable "y", let's prove that:

- First operation: Multiplying<u> the first equation</u> by -1 and add the equations together,

$x+y=7\\12x+y=5$

$x*(-1)+y*(-1)=7*(-1)\\12x+y=5$

$-x+-y=-7\\12x+y=5$

Adding the equations, we have:

$12x-x+y-y=5-7$

$11x+=5-7$

$11x+=-2$

$x=-\frac{2}{11}$

We can see that we can solve the problem using the first operation the operation.

- Third operation: Multiplying <u>the second equation</u> by -1 and add the equations together,

$x+y=7\\12x+y=5$

$x+y=7\\12x*(-1)+y*(-1)=5*(-1)$

$x+y=7\\-12x+-y=-5$

Adding the equations we have:

$-12x+x+y-y=-5+7$

$-11x=2$

$x=-\frac{2}{11}$

We can see that we can solve the problem using the third operation.

Also, we can see that in both equations the variable "y" has the same coefficient, the only operations that could work to solve the system using addition are the first and the third operation.

Have a nice day!

In the ecomienda system Spanish colonists were expected to do

Maurinko [17]

Answer: Encomienda was a system that was characteristic of the colonization of a country.

Explanation:

Specifically, it is a system used by the Spanish Crown to reward its colonizers with several people from conquered Indigenous areas. This system was most used during the Spanish colonization of the United States and the Philippines. Spain considered the conquered areas as its vassal territories. Several Indigenous people, therefore, had to work in the interest of the Spanish Crown. In return, they were promised protection from other tribes. The natives would thus pay their "taxes" in various goods such as food, metals and other necessities. Therefore, Encomienda represents the Spanish system of taxation of the conquered areas.

What do you think is the most important element of a story: setting, characterization, dialogue, or plot (events and action)? Wh

Veseljchak [2.6K]

I think the most important element of a story is the plot. To me the plot is what makes the story intriguing and fun to read. Without a plot I would personally find the story boring and wouldn’t want to read it.
