tolong jawabkan pake cara ya! 1) Nilai x yang memenuhi persamaan 2 log x - log y=1 dan persamaan log x + log y =8.

eliminasi
2.log x - log y = 1
log x + log y = 8
-------------------------- +
3.log x = 9
log x = 9/3
log x = 3
x = 10³
x = 1.000

2log x - log y = 1
log x²/y = log 10
x²/y = 10 ---> 10y = x²

log x + log y = 8
log xy = log 10^8
xy = 10^8
10yx = 10 . 10^8
x² . x = 10^9
x³ = (10³)³
x = 10³

10y = x²
10y = 10^6
y = 10^5

(x,y) = (10^3 , 10^5)
