Question

tìm x

Answer 1

5: =>x-35=81+11=92

hay x=127

6: =>x+35=33

hay x=-2

7: x=-120+88=-32

8: =>x+61=120

hay x=59

Answer 2

giải chi tiết nha

 

Answer 3

`5)(x-35)+(-81)=11`

`x-35=11-(-81)=92`

`x=92+35=127`

__________________________________________________________

`6)18-(x+35)=-15`

`x+35=18-(-15)=33`

`x=33-35=-2`

__________________________________________________________

`7)x+(-88)=-120`

`x=-120-(-88)=-32`

__________________________________________________________

`8)x-(-61)=120`

`x=120+(-61)=59`

__________________________________________________________

`9)(-111)-x=38+(-12)`

`(-111)-x=26`

`x=(-111)-26=-137`

__________________________________________________________

`10)120+(x-55)=11-66`

`120+(x-55)=-55`

`x-55=-55-120=-175`

`x=-175+55=-120`

Answer 4

:v chữ thưa qá 

\(5)\\ \left(x+35\right)+\left(-81\right)=11\\ x+35=11+81\\ x+35=92\\ x=92-35\\ x=57\\ 6)\\ 18-\left(x+35\right)=-15\\x+35= 18+15\\ x+35=33\\ x=33-35\\ x=-2\)

\(7)\\ x+\left(-88\right)=-120\\ x=\left(-120\right)+88\\ x=-32\\ 8)\\ x-\left(-61\right)=120\\ x+61=120\\ x=59\)

\(9)\\ \left(-111\right)-x=38+\left(-12\right)\\ \left(-111\right)-x=26\\ x=-111-26\\ x=-137\\ 10)\\ 120+\left(x-55\right)=11-66\\ 120+\left(x-55\right)=-55\\ x-55=-55-120\\ x-55=-175\\ x=-175+55\\ x=-120\)
