26 - 3 ( x + 1 ) = 14
=> 26 - 3x - 3 = 14
=> 23 - 3x = 14
=> 3x = 23 - 14
=> 3x = 9
=> x = 9 : 3
=> x = 3
Vậy x = 3
26-3.(x+1)=14
3.(x+1)=26-14
x+1 =12:3
x =4-1
x =3
hok tot nha
26 - 3 .(x+1)=14
3.(x+1) =26-14
3.(x+1)=12
x+1=12:3
x+1 =4
x=4-1
x=3
Vậy x=3
3.(x+1)=26-14
3.(x+1)= 12
x+1 =12:3
x+1=4
x=4-1
x=3
26-3.(x+1)=14
3.(x+1)=26-14
3.(x+1)=12
x+1 =12:3
x+1 =4
x = 4-1
x = 3
26-3.(x+1)=14
3.(x+1)=26-14
3.(x+1)=12
(x+1)=12:3
(x+1)=4
x =4-1
x =3
Vậy x =3
26 - 3 . (x+1) = 14
3. ( x+1) = 26-14
3. ( x+1) = 12
x+ 1 = 12 : 3
x+ 1 = 4
x = 4-1
x = 3
Vậy x bằng 3
