11 – (15 + 11) = x – (25 – 9)
11 -15 -11 = x – 16
-15 = x – 16
-15 + 16 = x
X = 1
11 - ( 15 + 11 ) = x - ( 25 - 9 )
11 - 26 = x - 16
- 15 = x - 16
- 15 + 16 = x
1 = x.
Nhớ tick mình nhé !
a, 11 - ( 15 + 11 ) = x - ( 25 - 9 )
11-15-11=x-25+9
-15=x-16
x=1
b, 2 - x = 17 - ( - 5 )
2-x=22
x=-20
c, x - 12 = ( - 9 ) - 15
x-12=-24
x=-12
d, 9 - 25 = ( 7 - x ) - ( 25 + 7 )
(7-x)-32=-16
7-x=16
x=-9
#H
11-(15+11)=x-(25-9)
11-26=x-16
-15=x-16
x= -15+16
x=1
vậy x=1
tick nha !!!!!!!
Ta co :
11-(15+11)=x-(25-9)
-15=x-(25-9)
-15=x-16
x=-15+16

lik e nhe
a,11-(15+21)=x-(25-9)
11-15-21=x-25+9
-x=-25+9-11+15+21

tick cho mk nha bạn
a)2-x=17-(-5)

a) 11-(15+11)=x-(25-9)
=> 11-15-11=x-16
=> -15 = x-16
=>x=1
b) 2-x=17-(-5)
=> 2-x=22
=>x=-20
c) x-12=-9-15
=>x-12=-26
=>x=-14
mik 2k5 nà bạn ^-^
a.11-26=x-16
-15=x-16
x=-15+16=1
b.2-x=22
x=2-22=-20
c.x-12=-24
x=-24+12=-12
\(11-\left(15+x\right)=x-\left(25-9\right)\)
\(11-15-x=x-\left(25-9\right)\)
\(11-15+\left(25-9\right)=x+x\)
\(12=2x\)
\(x=6\)
11-(15+x)=x-(25-9)
11-15-x=x-25+9
-x-x=-25+9-11+15
-2x=38
x=-19
