100 points! what is the solution to the system of equations? x+y=2 x-y=4 ( , )

(3, -1)

Step-by-step explanation:

The system of linear equations x+y=2 x-y=4 can be rewritten as

x+y=2

x-y=4

We can eliminate y by adding these two equations together:

x+y=2

x-y=4

2x = 6

Solving for x, x = 3.  

Now find y by subbing 3 for x in the first equation:

3 + y = 2.  Then y = -1.

The solution is (3, -1).

step-by-step explanation:

the options are kind of confusing. i can tell you what i see going on here when i look at the graph.

the class and exam medians are closely related, and it looks like the low outlier on the exam did pull the median lower. [tex][/tex]
