20105.(x-60)=20106
=>x-60=20106:20155
=>x-60=20106-5
=>x-60=2010
=>x=2010+60
=>x=2070
a) 720 : [41 - (2x - 5)] = 23 .5
b) 5x + 3(10 - x) + x = 45
c) |4 - 2x| = 6
d) (-3)x = - 27
2010^5 x ( x-60 ) = 2010^ 6
x-60=2010^6:2010^5
x-60= 2010
x=2010+60
x=2070
20105 . (x - 60) = 20106
x - 60 = 20106 : 20105
x - 60 = 2010
x = 2010 + 60
x = 2070
Vậy x = 2070
Ta có:
\(\frac{5}{1.6}+\frac{5}{6.11}+...+\frac{5}{\left(5x+1\right).\left(5x+6\right)}\)
\(=1-\frac{1}{6}+\frac{1}{6}-\frac{1}{11}+...+\frac{1}{5x+1}-\frac{1}{5x+6}\)
\(=1-\frac{1}{5x+6}\)
\(=\frac{5x+5}{5x+6}=\frac{2010}{2011}\)
\(\Rightarrow5x+5=2010\)
\(\Rightarrow5x=2010-5=2005\)
\(\Rightarrow x=2005:5=401\)
Vậy x=401
`Answer:`
\(\left(\frac{x+1}{2013}\right)+\left(\frac{x+2}{2012}\right)+\left(\frac{x+3}{2011}\right)=\left(\frac{x+4}{2010}\right)+\left(\frac{x+5}{2009}\right)+\left(\frac{x+6}{2008}\right)\)
\(\Leftrightarrow\frac{x+1}{2013}+1+\frac{x+2}{2012}+1+\frac{x+3}{2011}+1=\frac{x+4}{2010}+1+\frac{x+5}{2009}+1+\frac{x+6}{2008}+1\)
\(\Leftrightarrow\frac{x+2014}{2013}+\frac{x+2014}{2012}+\frac{x+2014}{2011}=\frac{x+2014}{2010}+\frac{x+2014}{2009}+\frac{x+2014}{2008}\)
\(\Leftrightarrow\frac{x+2014}{2013}+\frac{x+2014}{2012}+\frac{x+2014}{2011}-\frac{x+2014}{2010}-\frac{x+2014}{2009}-\frac{x+2014}{2008}=0\)
\(\Leftrightarrow\left(x+2014\right)\left(\frac{1}{2013}+\frac{1}{2012}+\frac{1}{2011}-\frac{1}{2010}-\frac{1}{2009}-\frac{1}{2008}\right)=0\)
\(\Rightarrow x+2014=0\)
\(\Leftrightarrow x=-2014\)
\(\left|x\right|=1+2+3+...+2010\)
\(\left|x\right|=\frac{\left(2010+1\right).2010}{2}\)
\(\left|x\right|=2011.1005\)
\(\left|x\right|=2021055\)
\(x=\pm2021055\)
\(2010^5\left(x-60\right)=2010^6\)
=> \(x-60=\frac{2010^6}{2010^5}=2010\)
=> x = 2010 + 60 = 2070
Vậy x = 2070
20105.( x - 60 ) = 20106
<=> x - 60 = 20106 : 20105
<=> x - 60 = 2010
<=> x = 2070
