Answer:
x=-5, y=-2. (-5, -2).
Step-by-step 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
Answer:
(-5, -2)
Step-by-step 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!
