Tìm x :
\(x+100=200+300\)
Tìm X,biết:
100 + 100 < 300 - X < 200 + 200
X=0
Tick nha !Nguyễn Khánh Duy
tìm x:300+(100-x)=200
300+(100-x)=200
100-x=200-300
100-x=-100
x=100-(-100)
x=-200
100 - x = 300 - 200
100 - x = 100
x = 100 - 100
x = 0
Vậy x = 0
k mk nha
Tìm x :
x + 300 = 200 x 3 - 100
x + 300 = 200 x 3 - 100
=> x + 300 = 600 - 100
=> x + 300 = 500
=> x = 500 - 300
=> x = 200
vậy x = 200
x+300=600-100
x+300=500
x=500-300=200 tk nha mik nha nhất!^_^
b) 200 x 4 = ...... 300 x 2 = ......
200 x 2 = ...... 300 x 3 = ......
400 x 2 = ...... 500 x 1 = ......
100 x 4 = ...... 100 x 3 = ......
b) 200 x 4 = .800..... 300 x 2 = ..600....
200 x 2 = .400..... 300 x 3 = ...900...
400 x 2 = ...800... 500 x 1 = ..500....
100 x 4 = ..400.... 100 x 3 = .300.....
x+100=200-300
x+300=200
x+100=-100
x = -100 - 100
x = -200
x+300=200
x = 200-300
x =-100
k nha!
x+100=-100
x=-100-100-200
x+300=200
x=200-300
x=-100
a)x+100=200-300
x+100=(-100)
x =(-100)-100
x =(-200)
b)x+300=200
x =200-300
x =-100
Tìm x: X * 100 + X* 200 + X * 300 + X * 400 + X * 500 + X * 512 = 2012
X x 100 + X x 200 + X x 300 + X x 400 + X x 500 + X x 512 = 2012
X x (100 + 200 + 300 + 400 + 500 + 512) = 2012
X x 2012 = 2012
X = 2012 : 2012
X = 1
thanks.
X * 100 + X* 200 + X * 300 + X * 400 + X * 500 + X * 512 = 2012
X * (100 + 200 + 300 + 400 + 500 + 512) = 2012
X * 2012 = 2012
X = 2012 : 2012
X = 1
Vậy X bằng 1
X x 100 + X x 200 + X x 300 + X x 400 + X x 500 + X x 512 = 2012
X x ( 100 + 200 + 300 + 400 + 500 + 512 ) = 2012
X x 2012 = 2012
X = 2012 : 2012
X = 1
x+100=200
x-100=200-300
x+100=200
x=200-100
x=100
x-100=200-300
x-100=-100
x=0
k mk nha
x + 100 = 200
x = 200 - 100
x = 100
x - 100 = 200 - 300
x - 100 = -100
x = -100 + 100
x = 0
x=200-100
x=100
x-100=200-300
x-100=-100
x=-100+100
x=0
500 + x = 100 + 500
300 - x = 300 + 200
400 - x = 200 + 400
500 + x = 100 + 500
500 + x = 600
x = 600 - 500
x = 1001
300 - x = 300 + 200
300 - x = 500
x = 300 - 500
x = -200
400 - x = 200 + 400
400 - x = 600
x = 400 - 600
x = -200
k mk nha mk k l
ại ^_^
500 + 100 = 100 + 500
300 + 200 = 300 + 200
400 + 200 = 200 + 400
500+x=100+500
vay x =100
300-x=300+200
vay x= - 200
400-x=200+400
vay x= -200
Tìm x biết
100 + x = 200 + 300
Ai k mình mình k lại
100 + x = 200 + 300
100 + x = 500
x = 500 - 100
x = 400
100+x=200+300
100+x=500
x=500-100
x=400
