Himpunan penyelesaian dari sistem persaaman ? 1/5y+1/2x=6 3/5x-1/2y=2

1/5y + 1/2x = 6
3/5x - 1/2y = 2

(kedua ruas dikali dengan 10)

2y + 5x = 60 |X6| 12y + 30x = 360
-5y + 6x = 20 |X5| -25y + 30x = 100
------------------ - ---------------------- -
37y = 260
y = 260/37

2y + 5x = 60
2 (260/37) + 5x = 60
520/37 + 5x = 60
5x = 60 - 520/37
5x = 2220 - 520/37
5x = 1700/37
x = 1700/37 : 5/1
x = 1700/37 x 1/5
x = 1700/185
