Question

Dgn cara eliminasi tlong carikan x dan y

Answer 1

1/x + 1/y = 10
5/x - 3/y = 26
yang atas dikali 5
5/x + 5/y = 50
5/x - 3/y = 26
dieliminasi dikurang
8/y = 24
8 = 24y
y= 1/3

disubtitusi kepersamaan awal:
5/x - 3/1/3 = 26
5/x - 9 = 26
5/x = 35
5 = 35x
x = 1/7

mohon dihitung lagi yaa semoga benar :)

Answer 2

Mis 1/x =a 1/y = b

a+b= 10
5a - 3b = 26
----------------
3a+ 3b=30
5a-3b=26
---------------+
8a = 56
a= 7
b = 10-7=3

1/x=7
x= 1/7
1/y=3
y=1/3
