a) 6 x 10 x 100 x 0 + 2017
= 0 + 2017
= 2017
b) 402 - 46 + 298 - 600 - 54
= (402 + 298) - (46 + 54) - 600
= 700 - 100 - 600
= 0

\(a,x+1=35:7+5\)
\(\Leftrightarrow x+1=10\)
\(\Leftrightarrow x=9\)
\(b,x:3=45:5\)
\(\Leftrightarrow x:3=9\)
\(\Leftrightarrow x=27\)
hok tốt!
a) \(x+1=35:7+5\)
\(\Rightarrow x+1=5+5\)
\(\Rightarrow x+1=10\)
\(\Rightarrow x=10-1\)
\(\Rightarrow x=9\)
Vậy x = 9
b) \(x:3=45:5\)
\(\Rightarrow x:3=9\)
\(\Rightarrow x=9\times3\)
\(\Rightarrow x=27\)
Vậy x = 27
_Chúc bạn học tốt_

A=1995x1995
=1994x1995+1995
B=1994x1996
=1994x1995+1994
Vì 1994x1995+1995>1994x1995+1994 nên A>B

\(x\times34+x\times89+x\times24+x\times56=46795\)
\(\Rightarrow x\times\left(34+89+24+56\right)=46795\)
\(\Rightarrow x\times203=46795\)
\(\Rightarrow x=46795:203\)
\(\Rightarrow x=230,5172414\)

\(\left(y+125\right)\times2=198\\ \Leftrightarrow y+125=198:2\\ \Leftrightarrow y+125=99\\ \Leftrightarrow y=99-125\\ \Leftrightarrow y=-26\)
=> x+29,8-930-205=0
=> x=0+205+930-29,8
=> x=1105,2
