Tentukan penyelesaian atau akar dari sistem persamaan berikut. 1/x - 1/y =3/10 dan 4/x + 5/y =3 Tolong di jawab yaa plisss

1/x - 1/y = 3/10 |×4| ==> 4/x - 4/y = 12/10
eliminasi
4/x - 4/y = 12/10
4/x + 5/y = 3
------------------------ _
-9/y = 12/10 - 3
-9/y = 12/10 - 30/10
-9/y = -18/10
y = -9×10/-18
y = 5
1/x - 1/5 = 3/10
1/x = 3/10 + 1/5
1/x = 3/10 + 2/10
1/x = 5/10
x = 10/5 = 2
