(x + x + x) + (1 +2 + 3) = 24
x × 3 + 6 = 24
x × 3 = 24 - 6
x × 3 = 18
x = 18 : 3
x = 6
vậy x=6
(x+1)+(x+2)+(x+3)=24
(x+x+x)+(1+2+3)=24
x.3+6=24
x=(24-6):3
x=6
(x + 1) + (x + 2) + (x + 3) = 24
( x + x + x ) + ( 1+2+3) = 24
( X x 3) + 6 = 24
X x 3 = 24 - 6
X x 3 = 18
X = 18 : 3
X = 6
(x+1)+(x+2)(x+3)=24
(x+x+x)+(1+2+3)=24
x3+6=24
x3=24-6
x3=18
x=18:3
=6
k cho mk nha bn tốt
(X+1)+(X+2)+(X+3)=24
(X+X+X)+(1+2+3)=24
X x 3 + 6 =24
X x 3=24-6
X x 3=18
X=18:3
X=6
ta có (x + 1) + (x + 2) + (x +3) = 24
x + 1 + x + 2 + x + 3 = 24
3x + 6 = 24
3x = 24 -6
3x = 18
x = 18 : 3
x = 6
