Tolong selesaikan HIMPUNAN PENYELESAIAN SPLDV MENGGUNAKAN METODE ELEMINASI 3x+3y=5 dan 2x+y=2

Answer 1

3x+3y=5. x 2
2x+y=2. x 3
_________ -

6x+6y=10
6x+3y=6
_____________-
3y=4
y=4/3


2x+y=2
2x=2-y
2x=2-4/3
2x=6/3 - 4/3
2x=2/3
x=1/3

Answer 2

3x + 3y = 5  | x2 |
2x + y = 2    | x3 |

6x + 6y = 10
6x + 3y = 6
----------------------
3y = 4
y = 4/3

2x + 4/3 = 2
2x = 2 - 4/3
2x = 2/3
x = 2/3 : 2 = 2/6 = 1/3
