Answer:
75%
Step-by-step explanation:
there are 4 3s in 12 and 9 is 3 of those 3s so 75%
There is no solution for the first one
if you eliminate y you get 2 equations
-13x - 13z = -25
-13x - 13x = -15
- there is no solution to theses
a23 means the element in the second row and the 3rd column
so its -5
<h3>Isolate y on both equations then equate </h3>
- x²-3x+2y=-4
- 2y=-x²+3x-4
- y=-x²/2+3/2x-2
Now you can equate it with second one to get x
9x + 27
-2y + 20
4x - 24
30x + 12xy
15x + 2 (?)
~ I’m not sure abt the last one! I’m sorry if they’re incorrect and I hoped this helps! ~
