Answer:

(-5, -2)

Explanation:

You can find the solution to the system by either doing substitution or elimination. Since it is already it standard form, the easier way that I am showing you is elimination.

- 8x - 3y = 46 First you subtract! not add because you must

- 8x + 9y = 22​ cancel 8 them out.

---- 6y=24

6 6

y=-2

to find x, just plug into either equation!

Answer:

x=-5, y=-2. (-5, -2).

Explanation:

-8x-3y=46

-8x+9y=22

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

3(-8x-3y)=3(46)

-8x+9y=22

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

-24x-9y=138

-8x+9y=22

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

-32x=160

x=160/-32

x=-5

-8(-5)-3y=46

40-3y=46

3y=40-46

3y=-6

y=-6/3

y=-2
