( 3000 - 200 - 600 - 2000 -200 ) x 1508,689

=                    0                      x 1508,689

=                                            0

k mk nha ^_-

Khó quá!!!

(3000-200-600-2000-200)x1508,689

=0x1508,689

=0

=40           

40 nhé

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

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

\(200-x\times\left(84-76\right):16=2000-1866\) 

\(200-x\times8:16=134\)

\(x\times8:16=200-134\)

\(x\times8:16=16\)

\(x\times8=16\times16\)

\(x\times8=256\) 

     \(x=256:8\) 

     \(x=32\) 

2000 + 2000 = 4000

42 + 42 = 84 

200 + 200 = 400 

~ k mình nha ! ~

^^

= 4000

= 84

= 400

2000+2000=4000

42+42=84

200+200=400

= 300 

k minh nhe

=3000

200 + 600 + 200 + 2000

= (200 + 600 + 200) + 2000

= 1000 + 2000

= 3000

k nha

x=100

100 tk m nhé

100 nha 

nho tk nha

x+1000-200=2000

x+1000=2200

x=2200-1000

x=1200

70-5.(x-3)=45

5.(x-3)=70-45

5.(x-3)=25

x-3=5

x=8

x+1 000 - 200 = 2 000 

x + 1000=2200

x=1200

vậy x=1200.

70-5.(x-3)=45

5.(x-3)=25

x-3=5

x=8.

vậy x=8.

x + 1000 - 200 = 2000

x + 1000 = 2000 + 200

x + 1000 = 2200

          x = 2200 - 1000

          x = 1200

70 - 5.(x - 3) = 45

       5.(x - 3) = 70 - 45

       5.(x - 3) = 25

           x - 3 = 25 : 5 

           x - 3 = 5

                x = 5 + 3

                x = 8
