100+200+500+300=?

100+200+500+300

=(200+300)+500+100

=500+500+100

=1000+100

=1100

100 +200+500+300=1100

=500 

k mình nha bn

:))

200 + 300 - 100 + 100 = 500

200+300-100+100=500

tk mk nha

2500 nha bn

k mk nha bn

thanks nhju

300+200+100+400=1000 nha ban

300 + 200 + 100 + 400

= ( 300 + 200 ) + ( 100 + 400 )

= 500 + 500

= 500 x 2

= 2500

x+100=200-200+100-100+300

x+100=300

x=300-100

x=200

tk mk mk tk lại

x + 100 = 200 - 200 + 100 - 100 + 300

x + 100 = 300

x          = 300 - 100

x          = 200

Vậy số tự nhiên x cần tìm là 200

x+100=200-200+100-100+300

x+100=0+0+300

x-200=0+300

x-200=300

x=300+200

x=500

100+200+300=600.

CHÚC BẠN HỌC GIỎI NHA

=600 mình nhanh nhất

bằng 600 nha

kq la 1000 nha

=10000

100 + 100 + 100 + 400 + 300

=     300     +     400      +       300

=          700       +       300

=               1000

x + 100 = 200 - 100 - 100

x + 100 = 0

x          = 0 - 100

x          = -100

Vậy x = - 100

x+100=200-100-100

x+100=0

x       =0-100

x       =-100

x+100=200-100-100

x+100=100-100

x+100=0

x=0-100

x=-100

x + 100 = 50 x 2 + 100 - 100 + 200 - 800 + 1 000

x + 100 = 100 + 100 - 100 + 200 - 800 + 1 000

x + 100 = 100 + 200 - 800 + 1 000

x + 100 =    ( -500) + 1 000

x + 100 = 500

x = 500 - 100

x = 400.

x+100=50.2+100-100+200-800+1000

x+100=100+100-100+200-800+1000

x+100=200-100+200-800+1000

x+100=100+200-800+1000

x+100=300-800+1000

x+100=-500+1000

x+100=500

x=500-100

x=400

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

\(x+100=200-500\)

\(x+100=-300\)

\(x=-300-100\)

\(x=-400\)

\(x-100=200-500\)

\(x-100=-300\)
