Question

-(2x + 24) + 211 = _123

làm ơn hãy giúp mình, please

Answer 1

-(2x+24)+211 = - 123 

-(2x+24) = -123 - 211 

-(2x+24) = - 334

2x+24 = 334

2x = 310

x = 155

Answer 2

-(2x+24)+211=-123

-2x-24+211=-123

-2x+187=-123

-2x=-123-187

-2x=-310

x=-310/-2=155

Vậy 'ba chấm'!

Answer 3

Ta có: \(-\left(2x+24\right)+211=-123\)

   \(\Leftrightarrow-2x-24=-123-211\)

   \(\Leftrightarrow-2x=-334+24\)

   \(\Leftrightarrow-2x=-310\)

   \(\Leftrightarrow x=115\)
