- ( x + 84 ) + 213 = 16 - 213

- ( x + 84 ) = - 229

=> x + 84 = 229 

x = 145

\(-\left(x+84\right)=-16-213\)

\(-\left(x+84\right)=-229\)

\(\Rightarrow x+84=229\)

\(x=229-84\)

\(x=145\)

\(-\left(x+84\right)+213=-16\)

\(-x-84+213=-16\)

\(-x-84=-16-213\)

\(-x-84=-229\)

                \(-x=-229+84\)

                    \(-x=-145\)

                        \(x=145\)

Vậy x=145

-(x+84)  =(-16)-213

-(x+84)  =(-229)

=>x+84 =229

x=145

      ~Học Tốt~

sau 213 còn cộng số nào nữa ko bn?

Nếu ko thì:

-(x + 84) + 213 = -16

-(x + 84) = (-16) - 213

-(x + 84) = -197

-x + -84 = -197

-x = (-197) - (-84)

-x = -113

Vậy x=113

-(x+84) + 213 = -16

-x-81+213= - 16

-x + ( -81 ) + 213 = -16

-x + 132 = -16

-x        = -148

x        = 148

vậy: x=148

HAPPY NEW YEAR.

-(x+84)+213=-16

=>-(x+84)=-16-213=-229

=>x+84=229

=>x=229-84=145

tick nha các pn

x+84-213 = 16

x= 16+213-84 = 145
 

-(x+84)+213=-16 

-(x+84)= -16-213

-(x+84)=-229

x+84=229

- ( x + 84 ) + 213 =  -16 

- ( x + 84) = -16-213

- ( x + 84 )=-229

- x -84 = -229

-x =-229 + 84

-x =-145

Vậy x = 145

-(x + 84) + 213 = -16

-(x + 84)          = -16-213

-(x + 84)          = -229

-x   - 84           = -229

229 - 84          = x

145                = x

Vay x=145

Ta có - ( x + 84 ) = - 16 - 213 

suy ra - ( x + 84 ) = - 229

suy ra - x - 84 = - 229

suy ra - x = - 229 + 84

suy ra - x = - 145

suy ra x = 145

Vậy x = 145

 -x - 84 + 213 = - 16

-x = -16 + 84 - 213

-x  = - 113

x = - 113 : -1

x = 113

xin loi tra loi sai roi x =145 moi dung

-(x+84)= -16 - 213

tick nha

Ta có :

\(-\left(x-84\right)+213=16\)

\(-\left(x-84\right)=16-213\)

\(-\left(x-84\right)=-197\)

\(=>x-84=197\)

\(x=197+84\)

\(x=281\)

\(-x-84+213=16\)

\(-x-84=16-213\)

\(-x-84=-197\)

\(-x=-197+84\)

\(-x=-113\)

\(=>x=113\)

-(x+84) + 213 =16

-(x+84) = 16 - 213

-(x+84)= -197

--> x+84 = 197

-->    x= 197-84

-->    x= 113

Vậy x=113
