100 x 3 + 400 . . . 100 +200 + 100 x 4
100 x 3 + 400 ... 100 + 200 + 100 x 4
= 100 x 3 + 400 = 700
= 100 + 200 + 100 x 4 = 700
=> 100 x 3 + 400 = 100 + 200 + 100 x 4
100 +400 + 100 + 200 + 50 + 100 x 0 = ?
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
Chúc bạn học tốt !

~~hok tốt~~
100 + 100 + 200 + 200 + 300 + 300 + 400 + 400
x + 100 = 400 - 200
\(x+100=400-200\)
\(x+100=200\)
\(x=200-100\)
\(x=100\)
