2) B= /3x-1/+/4y+2/-3x
3) C= /2x-1/+/2x+5/+2017
4) D= /x+3/+/2x-1/+/x-1/
Tim xthuoc Z biet:
1,|2x-5|-|2x+9|=0
2,|x+1|-|x+2|-|3-x|=7
3,|2x+3|+|3x+2|-|4-x|=10
tim x, y, z biet
1. \(\frac{x+y}{2015}=\frac{xy}{2016}=\frac{x-y}{2017}\)
2.\(\frac{2x+2}{3}=\frac{3y-1}{4}=\frac{4x+2}{5}\)va x+y+z=7
Tim x
\(\frac{x+2015}{5}+\frac{x+2016}{4}=\frac{x+2017}{3}+\frac{x+2018}{2}\)
2/ tim x
\(\frac{x+2015}{5}+\frac{x+2016}{6}=\frac{x+2017}{7} +\frac{x+2018}{8}\)
3/ tim x
\(\frac{1}{3}+\frac{1}{6}+\frac{99}{101}+\frac{1}{15}+... +\frac{1}{x\left(2x+1\right)}=\frac{1}{10}\)
a,Tìm x biết: ||3x-3|+2x+(-1)2016 |=3x+20170
b,Cho B= 1+ 1/2*(1+2)+1/3*(1+2+3)+1/4*(1+2+3+4)+...+1/x*(1+2+3+...+x)
Tìm số nguyên dương x để B= 115
1, tim GTLN cua A=13/(x+5)^2+7
2, tim GTNN cua B=|x+2017|+(y+3)^2+2017
3, cho a-1/2=b+3/4=c-5/6 va 5a-3b-4c=46. Tim a,b,c.
tim so huu ti x biet :
a)\(\left(2x-3\right)^4=\left(2x-3\right)^6\)
b) \(\left(3x+5\right)^3=\left(3x+5\right)^{2016}\)
c) \(\left(2x+1\right)^{2015}=\left(2x+1\right)^{2017}\)
Tim x biet: (3/4x+5)-(2/3x-4)-(1/6x+1)=(1/3+4)-(1/3x-3)
Tim so tu nhienx,biet rang:1/3+1/6+1/10+...+2/x•(x+1)=2015/2017
