X x 3 + X x 2 + X - 2389 = 3779
X x 3 + X x 2 + X - 2389 = 3779
6 x X-2389=3779
6x X=6168
x=6168 : 6=1028
Ủng hộ mk nha
X x 3 + X x 2 +X -2389=3779
X x (2+3+1) - 2389 = 3779
X x 6=3779+2389
X x 6= 6168
X=6168:6
X = 1028
X x 3 + X x 2 +X -2389=3779
Xx(3+2-2389)=3779
Xx(-2389)=3779
x=3779:(-2389)
x=-3779/2389
Vậy x=-3779/2389
X x 3 + X x 2 +X -2389=3779
Xx3+Xx2+Xx1 =3779+2389
Xx3+Xx2+Xx1 =6168
Xx(3+2+1 ) =6168
Xx6 =6168
x=6168:6
x=1028
X x 3 + X x 2 +X - 2389 = 3779
X x ( 3 + 2 - 1 ) = 3779 + 2389
X x 4 = 6168
X = 6168 : 4
X = 1542
ta có Xx3 + Xx2 +X -2389 =3779
=Xx(3+2+1)-2389=3779
=Xx6=6168
X=1028
X x 3 + X x 2 + X -2389 =3779
=>X x 3 +X x 2 + X =6168
=>X x (3+2+1)=6168
=>X x 6 = 6168
=> X = 1028
Nho k cho mk do nha
Tìm x: x*3+x*2+x-2389 =3779
x nhân 3+ x nhân 2 + x -2389=3779
x*3+x*2+x-2389=3779
=>x*3+x*2+x=3779+2389
=>x*3+x*2+x=6168
=>x*(3+2+1)=6168
=>x*6=6168
=>x=6168:6
=>x=1028
Vậy x=1028
Tìm x : x * 3 + x * 2 + x - 2389 = 3779
Trả lờ x : =
x*3+x*2+x-2389=3779
x*(3+2+1)=3779+2389
x*6=6168
x=6168:6
x=1028
X x 3 + X x 2 + X - 2389 = 3779
X = ?
giúp mình nhé
X x 3 + X x 2 + X - 2389 = 3779
X + X + X x 3 x 2 - 2389 = 3779
X + X + X x 6 - 2389 = 3779
X = (3779 - 2389) + 6
X = (1410 + 6) : 3
X = 1416 : 3
X = 472
X x 3 + X x 2 + X - 2389 = 3779
nhớ tích cho mình nhé
Tìm X biết X x 3 + X x 2 + X - 2389=3779
