=> 100 x 3 + 400 = 100 + 200 + 100 x 4 

= nhau . k mình nha

100 x 3 +400 = 100+200+100 x 4

k nha

x + 100 = 200 - 400 + 100

x + 100 = -100

x = -100 - 100

x = -200

x+100=200-400+100

x+100=-200+100

x+100=-100

x=-100-100

x=-200

\(x+100=200-400+100\)

ai giúp mình với

100 + 400 + 100 + 200 + 50 + 100 x 0 = ?

Giải:

   100 + 400 + 100 + 200 + 50 + 100 x 0 

=  100 + 400 + 100 + 200 + 50 + (100 x 0)

=  100 + 400 + 100 + 200 + 50 + 0

=       500       +     300       +    50

=                 800                  +   50

=                               850

Tk mk nhé!

x=500 nha

k mk và kết bạn nha

x + 100 = 600

         x  = 600 - 100

         x  = 500                                    ai k mk,mk k lai
