2: \(\Leftrightarrow\left(\dfrac{x+1}{12}-1\right)+\left(\dfrac{x+2}{13}-1\right)=\left(\dfrac{x+3}{14}-1\right)+\left(\dfrac{x+4}{15}-1\right)\)

=>x-11=0

=>x=11

3: \(\Leftrightarrow\left(\dfrac{x-85}{15}-1\right)+\left(\dfrac{x-74}{13}-2\right)+\left(\dfrac{x-67}{11}-3\right)+\left(\dfrac{x-64}{9}-4\right)=0\)

4 - ( 27 - 3 ) = x - ( 13 - 4 )

4 - 24 = x - 9

- 20 = x - 9

x = - 20 + 9

x = - 11

\(4-\left(27-3\right)=x-\left(13-4\right)\)

\(4-27+3=x-13+4\)

\(-20=x-13+4\)

\(-20-4=x-13\)

\(-24=x-13\)

\(-24+13=x\)

\(-11=x\)

\(4-\left(27-3\right)=x-\left(13-4\right)\)

\(4-\left(27+3\right)=x-9\)

\(-20=x-9\)

\(x=-20+9\)

\(x=-11\)

4 - ( 27 - 3 ) = x - ( 13 - 4 )

4 - ( 27 - 3 ) = x - 9

4 -  24         =   x - 9

x - 9            = 4 - 24

x - 9            = -20

x                 = -20 + 9

x                 = -11

Vậy x là -11.

4 - ( 27 - 3) = x - ( 13 - 4 )

4 - 24        = x - 9

- 20           = x - 9

x - 9          = - 20

x               = -11

vậy: x = -11

4 - (27 - 3) = x - (13 - 4)

4 - 24 = x - 9

-20 = x - 9

x - 9 = -20

x = (-20) + 9

x = -11

4 - (27 - 3) = x - (13 - 4)

4 - 24 = x - 9

-20 = x - 9

x - 9 = -20

x = (-20) + 9

x = -11

4 – (27 – 3) = x – (13 – 4)

4 – 27 + 3 = x – 13 + 4 (bỏ ngoặc)

4 – 27 + 3 + 13 – 4 = x (chuyển vế –13 và 4)

–27 + 16 = x

–11 = x.

Vậy x = –11.

tick nha

4-(27-3)=x-(13-4)

4-24=x-9

=>x-9=4-24

x-9=-20

x=-20+9

x=-11

4-(27-3)=x-(13-4)

=>-20=x-9

=>x=-20+9

=>x=-11

4-27+3=x-13+4

-20=x-13+4

x-13+4=-20

x-13=-20-4

x-13=-24

x=-24+13

x=-11

 4 - (27-3) = x - (13-4)

=.x=-11

x-9=4-24
