Tìm x
2012.| x-2011| +\(\left(x-2011\right)^2\)=2013.|2011-x|

\(2012\cdot|x-2011|+\left(x-2011\right)^2=2013\cdot|2011-x|\)

Tìm x

giải pt

\(0,05\left(\frac{2x-2}{2011}+\frac{2x}{2012}+\frac{2x+2}{2013}\right)=3,3-\left(\frac{x-1}{2011}+\frac{x}{2012}+\frac{x+1}{2013}\right)\)

Tìm số nguyên \(x\)nhỏ nhất thỏa mãn:

 \(\left(\frac{2011}{2012}+\frac{2012}{2013}+\frac{2013}{2011}\right).\left(x-2013\right)>3x-6039\)

Tìm x biết:

\(\left(\frac{1}{2}+\frac{1}{3}+...+\frac{1}{2012}+\frac{1}{2013}\right)\cdot x=\frac{2012}{1}+\frac{2011}{2}+\frac{2010}{3}+...+\frac{2}{2011}+\frac{1}{2012}\)

Giải phương trình 0,05(\(\left(\frac{2x-2}{2011}+\frac{2x}{2012}+\frac{2x+2}{2013}\right)=3,3-\left(\frac{x-1}{2011}+\frac{x}{2012}+\frac{x+1}{2013}\right)\)

bài 2 Tìm GTNN của biểu thức A=\(\text{x^2-5x+y^2+xy-4y+2012}\)

tìm x biết (x+2014)/2011 + (x+2013)/2012 = (x+2012)/2013 + (x+2011)/2014

Tìm x biết:

a) \(^{2^x+2^{x+1}+2^{x+2}+2^{x+3}=480}\)

b) \(\left(\frac{1}{2}+\frac{1}{3}+...+\frac{1}{2012}+\frac{1}{2013}\right).x=\frac{2012}{1}+\frac{2011}{2}+\frac{2010}{3}+...+\frac{2}{2011}+\frac{1}{2012}\)

2012*|x-2011|+(x-2011)^2=2013*|2011-x
