Question

Which equation results from adding the equations in this system?

Answer 1

Answer:

It's 3x=3

Step-by-step explanation:

I did it in edg!  But its correct

Answer 2

Answer:

The correct option is second one i.e 7x = 3

Therefore the results from adding the equation in this system is

$7x=3$

Step-by-step explanation:

Given:

Equations as

$2x+y=8$      .......................1

$5x-y=-5$        .......................2

To Find :

Result when adding equation 1 and 2 = ?

Solution

On adding equation 1 and 2 the "y" term will get cancel and the like terms will combine that is add (2x and 5x ) and ( 8 and - 5)  as shown below

           2x     +    y    = 8

           5x    -   y     = - 5

-------------------------------------------

           7x     + 0        =   3

---------------------------------------------

Therefore the results from adding the equation in this system is

$7x=3$
