5 - ( 12 - x ) = 129 - ( 6 + 129 )
5 - 12 + x = 129 - 6 - 129
( -7 ) + x = ( -6)
x = ( - 6 ) + 7
x = 1
Vậy x = 1
5-(12-x)=129-(6+129)
5-(12-x)=129-135
5-(12-x)=-6
12-x =5-(-6)
12-x=11
x=12-11
x=1
\(-\left(-129\right)+\left(-129\right)-301+12\)

Chúc bạn học tốt
/-28/ + (129 - 182 + 99) - (129 + 199 - 182)
= 28 + 129 - 182 + 99 - 129 - 199 + 182
= 129 - 129 + 182 - 182 + 99 - 199 + 28
= 0 + 0 + (-100) + 28
= -72
\(\left|-28\right|+\left(129-182+99\right)-\left(129+199-182\right)\)
\(=28+129-182+99-129-199+182\)
\(=28+129+\left(-182\right)+99+\left(-129\right)+\left(-199\right)+182\)
\(=\text{ }\left[129+\left(-129\right)\right]+\text{ }\left[\left(-182\right)+182\right]+\text{ }\left[99+\left(-199\right)\right]+28\)
\(=0+0+\left(-100\right)+28\)
\(=\left(-100\right)+28\)
\(=-72\)
59 + 64 = 36 + 63 + 59 _Sai_
129 + 157 - 29 =129 - 29 + 157 _Đúng_
129 + 157 - 29 = 157 + 129 - 29 _Đúng_
4 +16 x 25 = 16 + 4 x 25 _Sai_
21 + 49 : 7 = 49 + 21 : 7 _Sai_
(36 + 45 ) : 9 = (45+36 ) : 9 _Đúng_
(Cái này tính nhẩm là ra thôi bạn ạ! Đúng cho mình 1 tick nhé bạn!)
B=(-129.129).(-347.347).(-253.253)
B=0.0.0

sai thì thôi nha bạn ^^
\(x=96-12=84.\)
\(x=96-12=84\)
\(x=98-78=20\)
\(x=69-27=42\)
\(x=85-20=65\)
\(x=129-85=44\)
\(x=201-129=72\)
\(x=98+129=227\)
96 - x = 12
x = 96 - 12
x = 84
78 + x = 98
x = 98 - 78
x = 20
x + 27 = 69
x = 69 - 27
x = 42
x + 20 = 85
x = 85 - 20
x = 65
x + 85 = 129
x = 129 - 85
x = 44
x + 129 = 201
x = 201 - 129
x = 72
x - 129 = 98
x = 129 - 98
x = 31
k mình nha , Thank you !
Bài hát này là : Symphony bạn nhé!
I've been hearing symphonies
Before all I heard was silence
A rhapsody for you and me
And every melody is timeless
Life was stringing me along
Then you came and you cut me loose
Was solo singing on my own
Now I can't find the key without you
Bài 5:Thực hiện phép tính:
a)-(-129)+315+(-129)-215
b)(-25).(-38).8.(-125).(-4)
c)12.(35+18)-18.(12-35)
a. -(-129) + 315 + (-129) - 215
= 129 + (-129) + (315 - 215)
= 0 + 100
= 100
b. (-25).(-38).8.(-125).(-4)
= [ (-25).(-4) ] . [ (-125).8 ] . (-38)
= 100 . (-1000) . (-38)
= 3800000
c. 12.(35 + 18) - 18.(12 - 35)
= 12.35 + 12.18 - 18.12 + 18.35
= 12.35 + 18.35 + 12.18 - 18.12
= 35 . (12 + 18) + 0
= 35 . 30
= 1050
