ta có : X x ( 65 + 35 ) =6000
X x 100 = 6000
X = 6000 :100
X = 60
65*x+35*x=6000
x*(65+35)=6000
x*100=6000
x=6000:100=60
k mình nha bạn
65*x+35*x=6000
x*(65+35)=6000
x*100=6000
x=6000/100
x=60
65*x+35*x=6000
=> x*(65+35)=6000
x* 100=6000
=> x=6000:100
x=60
65*x+35*x=6000
x*(65+35)=6000
x*100 =6000
x =6000/100
x =60
65*x+35*x=6000
x*(65+35)=6000
x*100=6000
x=6000/100
x=60
mk đầu tiên k cho mk nha
x=60 nha
tk nhé
cảm ơn
