Tìm x
x + 200 = 400
x = 400 - 200
x = 200
x + 200 = 500 - 200
x + 200 = 300
x = 300 - 200
x = 100
tính nhanh :
100 x 200 + 200 x 500 + 200 x 400
100x200+200x500+200x400
=20000+100000+80000
=120000+80000
=200000
100 x 200 + 200 x 500 + 200 x 400
= 200 x ( 100 + 500 + 400 )
= 200 x 1000
= 200000
100x200+200x500+200x400
=20000+100000+80000
=120000+80000
=200000
x + 200 = 500 + 200
x + 200 = 500 + 200
x + 200 = 700
x = 700 - 200
x = 500
x+200=500+200
x+200=700
x=700-200
x=500
x+200=500+200
x+200=700
x=500
vậy x = 500.
bạn học giỏi nha, k nha.
500 + 500 = ?
100 + 100 = ?
200 + 200 = ?
2000 x 20 = ?
500 + 500 = 1 000
100 + 100 = 200
200 + 200 = 400
2 000 x 20 = 40 000
500 + 500 = 1000
100 + 100 = 200
200 + 200 = 400
2000 x 20 = 40000
500+500=1000
100+100=200
200+200=400
2000x20=4000
k mình nha
x + 500 = 200 + 100 - 200
x+500=100
x =100-500
x =-400
mk nha.
Năm mới chúc các bn hok giỏi mạnh khỏe nha ^ _^
x + 500 = 200 + 100 - 100
x + 500 = 100
x = 100 - 500
x = -400
ai k mk ,mk k lai,nho kb jun nha
x + 200 = 500 + 200
x + 200 = 500 + 200
x + 200 = 700
x = 700 - 200
x = 500

x = 700 - 200
x = 500
x+100=200-500
x-100=200-500
ai k mk mk k lai
3 cái nhé
a) x= -300 -100
x = -400
b) x= -300 +100
x= -200
1)x+100=200-500
x+100=-300
x=-300-100
x=-400
2)x-100=200-500
x-100=-300
x=-300+100
x=-200
\(x+100=200-500\)
\(x+100=-300\)
\(x=-300-100\)
\(x=-400\)
\(x-100=200-500\)
\(x-100=-300\)
\(x=-300+100\)
\(x=-200\)
Tìm x :
x + 200 = 500 - 200
x+200=500-200
x+200=300
x=300-200
x=100
k mk nhé,đi mak đi mak
