Step-by-step explanation:
| 1 3 1 | x | 2 -2 |
| -2 1 0 | | 3 5 | =
| 4 1 |
2 x 3 3 x 2 = 2 x 2
Result Multiply rows by columns and simplify
| (1 x 2) + (3 x 3) + (1 x 4) (1 x -2) + (3 x 5) + (1 x 1) |
| (-2 x 2) + (1 x 3) + (0 x 4) (-2 x -2) + (1 x 5) + (0 x 1)|
Simplification
| 2 + 9 + 4 -2 + 15 + 1 |
| -4 + 3 + 0 4 + 5 + 0 |
Result
| 15 14 |
| -1 9|

(6x-y)-(6x+2y)=50-46
-3y=4
y=-4÷3
=-4/3
x=[23-(-4/3)]÷3
=24/1/3÷3
=73/3÷3

x----chickens
y----ducks
50x+30y=550
44x+36y=532
x=11-3/5y
44x+36y=532
x=11-3/5y
44(11-3/5y)+36y=532
x=11-3/5y
484+48/5y=532 /*5
x=11-3/5y
2420+48y=2660
x=11-3/5y
48y=2660-2420
x=11-3/5y
48y=240 //48
x=11-3/5y
y=5
x=11-3/5*5
y=5
x=8----chicken
y=5-----duck
Answer:
x>-3-y
Step-by-step explanation:
subtract y from both sides
