bạn tk mk nha, thank.......
Tìm x :

Tìm x:
\(x+100=500-200\)
\(x+100=300\)

vay x =100
300-x=300+200
vay x= - 200
400-x=200+400
vay x= -200
tìm x biết:
X+ 200 = 500
x + 200 = 500
x = 500 - 200
x = 300
ai tk mk mk tk lại
tính nhanh :
100 x 200 + 200 x 500 + 200 x 400
100x200+200x500+200x400
=20000+100000+80000
=120000+80000
=200000
100 x 200 + 200 x 500 + 200 x 400
= 200 x ( 100 + 500 + 400 )
= 200 x 1000
= 200000
100x200+200x500+200x400
=20000+100000+80000
=120000+80000
=200000
