Tim 2 STN x,y biet
2(x-3) +2y =0
Tim x;y thuoc N biet (x-1)(2y+3)=26
tim x va y biet ti so cua x va y la 3/4 va4x-2y la 7
Tim STN x,y biet :(3x+2).(2y+3)=1
(x+2).(2y+3)=12
Ai lam dung minh se tick cho
1) tim stn x biet rang (x+4).(23-x)=0
2) tong cac chu stn le tu 1 den 999 la
tim cac stn x, y biet: (2^x+1).(2^x+2)=3^y+305
Tìm các STN x và y, sao cho (x-2).(2y+3)=26
tim stn x,y sao cho x-3=xy+2y
tim y , x biet
( x - 1) ( 2y + 3 ) = 24
( x- 5 ) ( x + y ) = 12
( x + 1 ) ( x + 2 ) + ... + ( x +100 ) = 5750
Tim so nguyen to p de : p + 1, p + 2, p + 3 , p + 5 cung la so nguyen to
Cac ban giup minh nhe ! Hom nay minh phai di hoc roi
