kakak kakak.. bisa ga tolong aku ngerjain ini

Semoga membantu........

Eliminasi x :
1/x + 1/y = 10 || × 5
5/x - 3/y = 26 || × 1
⤵
5/x + 5/y = 50 - (5/x - 3/y = 26)

5/x + 5/y = 50
5/x + 3/y = -26
___________—
2/y = 76
y = 2/76
[ y = 1/38 ] ⬅substitusi ke 1/x + 1/y = 10

1/x + 1/y = 10
1/x + 1/(1/38) = 10
1/x + 38 = 10
1/x = 10 - 38
1/x = -28
[ x = -1/28 ]

Nilai x = -1/28
