#TThuHuongg
Tìm X biết 720:(X x 2 + X x 3) = 2x3
tìm X :
720 : ( X x 2+ X x 3)= 2x3
720 : (X x 2+ X x 3) = 2 x3
Toán nâng cao : 720 : ( a x 3 + a x 5 ) = 2 x 3
a x 5 + a = 360 : 6
720 : ( a x 2 + 3 ) = 2 x 3
720: (x+3+x x 5) =6 giup toi tim x voi nhe
y x 5 + y x 2 + y = 720
( X x 3 : = 5 + 2 X x 8 - 22 = 13 x 2
720 : ( X x 5 ) = 2* 3 X x 13 + 6 = 84
giúp mình nha
Tim x biet: 720:(x + 3 + x x 5) =6 giup toi giai bai toan nay voi
