Question

2log x - 3log y = 22
Log x - log y = 1

Alguien sabe? (╥_╥)

Answer 1

2log x - 3log y = 22 +
Log x - log y = 1...........(-2)
--------------------------------
2log x - 3log y = 22 +
-2Log x + 2log y =-2
-------------------------------
-log y =20
log y =-20


hallando log x en Log x - log y = 1
Log x - (-20) = 1
Log x + 20 = 1
Log x = 1-20
Log x = -19
