Question

Which equation results from adding the equations in this system? 11 x minus 3 y = -17. Negative 4 x + 3 y = - 18.

- 7 x = negative 35
- 7 x = 35
7 x = negative 35
7 x = 35

Answer 1

C

Explanation:

did test

Answer 2

Therefore the results from adding the equation in this system is

`7x=-35`

Explanation:

Given:

Equations as

`11x-3y=-17` .......................1

`-4x+3y=-18` .......................2

To Find :

Result when adding equation 1 and 2 = ?

Solution

On adding equation 1 and 2 the "3y" term will get cancel and the like terms will combine that is add (11x and -4x ) and ( -17 and - 18) as shown below

11x - 3y = -17

-4x + 3y = - 18

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

7x + 0 = - 35

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

Therefore the results from adding the equation in this system is

`7x=-35`
