Bài 2:Tim x:
a x + 4 + 9000 + 600 =9654
b x +86 = 40000 + 9000 + 100 + 80 + 6
a,
x+4+9000+600=9654
x+4+9600=9654
x+9604=9654
x=9654-9604
x=50
b,
x+86=40000+9000+100+80+6
x+86=49186
x=49186-86
x=49100
k mk nha các bn
x=50
a,
x+4+9000+600=9654
=> x+ 9604=9654
=> x=9654-9604=50
b x+86 = 49186
x= 49186-86= 49100
a,
x+4+9000+600=9654
x+4+9000 =9654 - 600
x+4+9000 =9054
x+4 =9054-9000
x+4 =54
x =54-4
x = 50
b,
x+86 =40000 + 9000 + 100 +80 + 6
x+86 =49186
x =49186 - 86
x =49100

( Ai nhanh mình tick ! )
48000-(2500×2+9000×3+9000×2÷3)
48 000 - ( 25 000 x 2 + 9 000 x 3 + 9 000 x 2 : 3 )
= 48 000 - ( 5 000 + 27 000 + 6 000 )
= 48 000 - 38 000
= 10 000
48000-(2500*2+9000*3+9000*2/3)
=48000-(5000+9000(3+2/3))=48000-(5000+18000)=48000-23000=25000
Tính nhanh:
48000 - (2500. 2 + 9000 . 3 . 9000 . 2 : 3)
9000 x 10000
98 + x = 9000
98 + x = 9000
x = 9000 - 98
x = 8902
