11 - (x+48) = 97
-(x+48) + 213 = -16
tìm x
-213 + x - 68 = -48
-213 + x - 68 = -48
x = -48 +213 +68
x = 233
-213+x-68= -48
-213+x = -48+68= 20
x = 20- (-213)
x =233
-213 + x - 68 = -48
=> x = -48 + 213 + 68
=> x = 233
vậy_
Tim x biet :
c ) - ( x + 48 ) + 213 = -16
- (x + 48) + 213 = -16
- (x + 48) = -16 - 213
- (x + 48) = -229
=> x + 48 = 229
=> x = 229 - 48
=> x = 181
-(x+48)+213=-16
-x-48=-16-213
-x-48=-229
-x=-229+48
-x=-181
x=181
Nhớ tk phát nhé.
-(x+48)+213=-16
-(x+48) =-16+(-213)
-x-48 =-229
-48+229 =x
\(\Rightarrow\)x =181
461+(x-45)=387
11-(-53+x)=97
-(x+84)+213=-16
a) 461+x-45=387
<=> 416+x=387
<=> x= -28
b) 11+53-x=97
<=> 64-x=97
<=>x=-33
c) -x-84+213=-16
<=>-x+129=-16
<=> x=145
461 + (x - 45 ) = 387
11 - (-53 +x) = 97
- ( x+84 ) + 213 = -16
tìm x
461 + (x - 45) = 387
x - 45 = 387 - 461
x - 45 = -74
x = -74 + 45
x = -29
11 - (-53 + x) = 97
-53 + x = 11 - 97
-53 + x = -86
x = -86 - -53
x = -33
- (x+84) + 213 = -16
x - 84 + 213 = -16
x - 84 = -16 - 213
x - 84 = -229
x = -229 + 84
x = -145
461 + ( x - 45 ) = 387
x - 45 = 387 - 461
x - 45 = - 74
x = - 74 + 45
x = - 29
Vậy x = - 29
11 - ( - 53 + x ) = 97
- 53 + x = 11 - 97
- 53 + x = - 86
x = - 86 - ( - 53 )
x = - 33
Vậy x = - 33
