Tìm x,y.z biết (x-2016)^2016+(y-2017)^2018 +/x-y+z/=0
Tìm x, biết:
a) | x - 2017 | = 2017 - x
b) | x - 2016 | + | x - 2017 | = 2018
c) | x - 1 | + | x + 3 | = 4
tìm x,y biết rằng |x-2015|+|x-2016|+|y-2017|+|x-2018|=3
Tìm x biết:
\(\frac{x}{2018}+\frac{x+1}{2017}+\frac{x+2}{2016}+\frac{x+3}{2015}=-4\)
Tìm giá trị nhỏ nhất
P = 2018/x^2+2x+2017
Q = a^2018+2017/a^2018+2015
A = (x-3y)^2020+(y-2018)^2018
B = (x+y-5)^8+(x-2y)^4+2016
C = \x-2017\+\x-2018\
D = \x-2010\+\x-2011\+\x+2012\
Tìm x biết :
\(\frac{x+2015}{5}+\frac{x+2016}{4}=\frac{x+2017}{3}+\frac{x+2018}{2}\)
x/2015+x/2016+x/2017=x/2018. tìm x
Tìm x,y biết :
\(|x-2015|\)+\(|x-2016|+|x-2017|+|x-2018|=3\)
TÌM X BIẾT : \(\frac{x+2}{2018}+\frac{x+3}{2017}+\frac{x+4}{2016}=-3\)
