x=100

100 tk m nhé

100 nha 

nho tk nha

2000-x-100=300

2000-x=400

x=2000-400

x=1600

ta có: 2000-x-100+200=500

=>2000-x-100             =300

=>2000-x                   = 400

=>x                          =1600

vậy: x=1600

ai tk mk rồi mk tk lại hứa luôn.

=>2000-x-100=500-200

=>2000-x-100=300

=>x-100=300+100

=>2000-x=400

=>x=2000-400

x=1600

Vậy x=1600

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

\(x+100=200-500\)

\(x+100=-300\)

\(x=-300-100\)

\(x=-400\)

\(x-100=200-500\)

\(x-100=-300\)

\(x=-300+100\)

\(x=-200\)

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

= 830 nha bạn

\(100+500+20+200+100=920\)

Ủng hộ nhé

10+500+20+200+100

=510+20+200+100

=530+200+100

=730+100

=830

1400 Nha

100+100+200+200+500+500=1600

100 + 100 + 200 + 200 + 500 + 500 = 1600

x+500=100

x       =100-500

x       =-400

mk nha.

Năm mới chúc các bn hok giỏi mạnh khỏe nha ^ _^

x+500=100

x=100-500

x=-400

x + 500 = 200 + 100 - 100

x + 500 = 100

x = 100 - 500 

x = -400

ai k mk ,mk k lai,nho kb jun nha

=100-500:[-20+(-30)*1]+200

=300-500:[-50]

=300+10

=310

a, 515 = 500 + 15                         b, 150 + 50 < 200 + 20

    52 + 100 > 100 + 25                      147 +47 > 200 - 46
