\(a,-152-\left(3x+1\right)=\left(-2\right).\left(-77\right)\)

\(-152-\left(3x+1\right)=154\)

\(3x+1=-152-154\)

\(3x=306\)

\(x=-102\)

Vậy \(x=-102\)

\(b,234+\left(-334-x\right)=500\)

\(-334-x=266\)

\(x=-600\)

Vậy \(x=-600\)

\(c,\left(567-x\right)+121=-641\)

\(567-x=-762\)

\(x=1329\)

Vậy \(x=1329\)

Làm lại câu a :

a, -152-(3x+1)=(-2).(-77)

-152-(3x+1)=154

3x+1=-306

3x=-307

x=-307/3

Vậy x=-307/3

a,-152-(3x+1)=(-2).(-77)

   -152-(3x+1)=154

     3x+1=-152-154

     3x+1=-306

     3x=-307

     x=-307/3

b,234+(-334-x)=500

   -334-x=500-234

   -334-x=266

    x=-334-266

    x=-600

c,(567-x)+121=-641

    567-x=-641-121

    567-x=-762

    x=567-(-762)

    x=1329

567 + 567 . 101 - 567 - 567

= 567 ( 101 - 1 )

= 567 . 100

= 56700 nhé bạn

Giúp dùm vs ạ

567 x 34 + 567 x 67 x 567 - 567

= 567 x 34 + 567 x 37989  - 567

= 567 x ( 34 + 37989 ) - 567

= 567 x 38023 - 567

= 21559041 - 567

= 2558474

\(567\times34+567\times67-567\)

\(=567\times34+567\times67-567\times1\)

\(=567\left(34+67-1\right)\)

\(=567\times100=56700\)

A)223459

B)567995

a) Số lớn nhất là : 223 459

b) Số lớn nhất là : 567 995

Đây nhé:

N=0 nha

\(-567-\left(-113\right)+\left(-69\right)-\left(113-567\right)\)

\(=-567+113+\left(-69\right)-113+567\)

\(=\left(-567+567\right)+\left(113-113\right)+\left(-69\right)\)

\(=\left(-69\right)\)

\(-567-\left(-113\right)+\left(-69\right)-\left(113-567\right)\)

\(=-567+113-69-113+567\)

\(=\left(-567+567\right)+\left(113-113\right)-69\)

\(=0+0-69=-69\)

-7 + 2x = -37 - (-26)

\(\frac{1234\times567-667}{567+1234\times566}=\frac{1234\times\left(566+1\right)-667}{567+1234\times566}=\frac{1234\times566+1234-667}{567+1234\times566}\)

\(=\frac{1234\times566+567}{567+1234\times566}=1\)
