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

<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!

Answer and Explanation:

In "Flowers for Algernon," the main character is Charlie Gordon, a man who undergoes surgery to improve his intelligence. Before the procedure, Charlie's I.Q. was 68. At a certain point in the story, three different doctors try to explain to Charlie what I.Q. is, but they have different opinions on the matter.

<u>Dr. Nemur says the I.Q. of a person shows how smart that person is. Dr. Strauss, on the other hand, claims that Dr. Nemur is wrong, and that an I.Q. shows how smart a person can get. That it is like the numbers written on a measuring cup - we still need to fill the cup with something. Confused, Charlie talks to Dr. Burt, who says the other two doctors could be wrong. According to Burt, I.Q. can measure several different things, including things a person has already learned, but it is not a good measure for intelligence.</u>
