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

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

x + 100 = 200 - 300

x + 100 = -100

x = ( -100 ) - 100

x = -200.

x + 100 = 200 - 300

x + 100 = -100

          x = -100 - 100

          x = -200

k cho tớ trước

x + 100 = 200 - 300

x + 100 = -100

x = -100 - 100

x = -200

x + 100 = 200 - 300

x + 100 = - 100

x          = -100 - 100

x           = 200

 Vậy x = 200

x+100=200-300

x+100=-100

x=-100-100

x=-200

x+100=200-300

x+100=-100

x=-100-100

x=-200

x + 1000 = 300 - 200 + 100

x + 1000 = 200

x = 200 - 1000

x = -800

x+1000=300-200+100

x+1000=100-100

x+1000=0

x=0-1000

x=-1000

x + 1000 = 300 - 200 + 100

x + 1000 = 0

x            = 0 - 1000

x            = - 1000

 Vậy x = -1000

x = 50

k mk,mk k lai bn

50 nhe co ai ket ban voi minh ko

100 + 100 + 200 + 300

= 100 x 2 + 200 + 300

= 200 + 200 + 300

= 200 x 2 + 300

= 400 + 300

= 700

= 700 đúng ko

100 + 100 + 200 + 300

= 200 + 200 + 300

= 400 + 300 

= 700
