a) 6x : 3 - 5 = 41

2x - 5 = 41

2x = 41 + 5

2x = 46

x = 46 : 2

x = 23

b) 1 000 000 000 : x = 500

x = 1 000 000 000 : 500

x = 2 000 000

\(a)6x:3-5=41\)

\(\Rightarrow6x:3=46\)

\(\Rightarrow6x=138\)

\(\Rightarrow x=23\)

\(b)1000000000:x=500\)

\(\Rightarrow x=1000000000:500\)

\(\Rightarrow x=20000000\)

tk mik nhé 

hok tốt

= 0 nha . ti ck mk đi ko mk khóc đó

=0 do ban

10000000000 x 0 x 2 + 3 - 30000 - 30000

= 0 x 2 + 3 - 30000 - 30000

= 3 - 30000 - 30000

= (-29997) - 30000

= (-59997)

1000000000 . 1000000000 = 1000000000000000000

1000000000 . 1000000000 =  1000000000² = 1000000000000000000

k cho mik nha

=1000000000000000000

1000000000 : 50 + 100000 : 2 = 10050000
