Answer:

1  Multiply the first equation by -1 then add the equations together

3. Multiply the second equation by -1 then add the equations together

4. Multiply the first equation by -2 then add the equations together

5. Multiply the first equation by 2 the second by -1 then add the equations together

Step-by-step explanation:

x+y = 7

2x+y = 5


1  Multiply the first equation by -1 then add the equations together

-x+-y = -7

2x+y = 5

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

x    =-2   then solve for y


2.  Multiply the second equation by -1 first equation by -1 then add the equations together

-x+-y = -7

-2x-y = -5

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

-3x -2y = -12

Still have both variables


3. Multiply the second equation by -1 then add the equations together

x+y = 7

-2x-y =- 5

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

-x = 2


4. Multiply the first equation by -2 then add the equations together

-2x+-2y = -14

2x+y = 5

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

    -y = -9


5. Multiply the first equation by 2 the second by -1 then add the equations together

2x+2y = 14

-2x-y = -5

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

y = 9
