- ( x + 84 ) + 213 = -16
giải nhanh nhá
tìm x biết : -(x+84)+213= (-16)
làm nhanh dùm mo
-(x+84)+213=(-16)
-(x+84) =-16-213
-x-84 =-229
-x =-229+84
-x =-145
x =145
-(x+84)+213=-16 .
Tìm x nha . ai nhanh nhất mk tick cho .
-(x+84)+213= -16
-x+84 = -16 - 213
-x+84 = -229
x = -229 - ( -84)
x = -145
-(x+84)+213=-16
-x-84+213=-16
-x-84=16-213
-x-84=-229
-x=229+84
-x=-145
=> x=145
x - 320 : 32 = 25 . 16
giải giúp mik vs ạ
x - 320 : 32 = 25 . 16
x - 10 = 400
x = 400 + 10
x = 410
\(=>x=\left(320:32\right)+\left(25.26\right)=10+400=410\)
213-2[x+84]+[x+84]=0
=> 213 + (x + 84).(-2 + 1) = 0
=> 213 - (x + 84) = 0
=> 213 - x - 84 = 0
=> 129 - x = 0
=> x = 129
Tìm x, biết :
- ( x + 84 ) + 213 = -16
| x + 2 | = 341 + ( - 25 )
| x + 7 | = | - 15 |
19 - | x - 1 | = 4
giúp mk nha ! ai nhanh mk tick
a) -x - 84=-16-213
-x-84=-229
-84+229=x
145 =x
b) /x+2/= 316
suy ra x+2=316 hoac x+2=-316
* x+2 = 316
x = 314
* x+2 =-316
x = -318
vay x=314 hoac x=-318
c) /x+7/=15
suy ra x+7=15 hoac x+7=-15
x+7=15
x = 8
x+7= -15
x = -22
vay x= 8 hoac x=-22
d) 19-4=/x-1/
15=/x-1/
suy ra x-1=15 hoac x-1=-15
x-1=15
x = 16
x-1=-15
x= -14
vay x=16 hoac x=-14
\(-\left(x+84\right)+213=-16\)
\(=>-x-84+213=-16\)
\(=>-x=-16+84-213=-145\)
\(=>x=145\)
\(\left|x+2\right|=341+\left(-25\right)\)
\(=>\left|x+2\right|=341-25=316\)
\(=>\orbr{\begin{cases}x+2=316\\x+2=-316\end{cases}}\)
\(=>\orbr{\begin{cases}x=314\\x=-318\end{cases}}\)
\(\left|x+7\right|=\left|-15\right|\)
\(=>\left|x+7\right|=15\)
\(=>\orbr{\begin{cases}x=15-7\\x=-15-7\end{cases}}\)
\(=>\orbr{\begin{cases}x=8\\x=-22\end{cases}}\)
\(19-\left|x-1\right|=4\)
\(=>\left|x-1\right|=19-4=15\)
\(=>\orbr{\begin{cases}x-1=15\\x-1=-15\end{cases}}\)
\(=>\orbr{\begin{cases}x=16\\x=-14\end{cases}}\)
-(x+84)+213=-16
- ( 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=229-84
x=145
~Học Tốt~
- ( x + 84 ) + 213 + = - 16
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
\(-\left(x+84\right)+213=-16\)
\(-x-84+213=-16\)
\(-x+129=-16\)
\(x=129+16\)
\(x=145\)
- ( X + 84 ) + 213 = - 16
- ( X + 84 ) = ( - 16 ) - 213
- ( X + 84 ) = 197
- X = 197 -84
- X = 113
= > X = - 113 HOẶC 113
k cho Sarah Lalle y nhé !
