Bài 1: tìm x
a)\(\left|3x-5\right|=4\)
b)\(\dfrac{x+1}{10}+\dfrac{x+1}{11}+\dfrac{x+1}{12}=\dfrac{x+1}{13}+\dfrac{x+1}{14}\)
c)\(\dfrac{x+4}{2000}+\dfrac{x+3}{2001}=\dfrac{x+2}{2002}+\dfrac{x+1}{2003}\)
Bài 2: Tính
a)\(\dfrac{\dfrac{1}{9}-\dfrac{1}{7}-\dfrac{1}{11}}{\dfrac{4}{9}-\dfrac{4}{7}-\dfrac{4}{11}}+\dfrac{\dfrac{3}{5}-\dfrac{3}{25}-\dfrac{3}{125}-\dfrac{3}{625}}{\dfrac{4}{5}-\dfrac{4}{25}-\dfrac{4}{125}-\dfrac{4}{625}}\)
b)\(\dfrac{1}{100.99}-\dfrac{1}{99.98}-\dfrac{1}{98.97}-...-\dfrac{1}{3.2}-\dfrac{1}{2.1}\)
c)\(\dfrac{\left(\dfrac{3}{10}-\dfrac{4}{15}-\dfrac{7}{20}\right).\dfrac{5}{19}}{\left(\dfrac{1}{14}+\dfrac{1}{7}-\dfrac{-3}{35}\right).\dfrac{-4}{3}}\)
Tìm x:
x+1/10 + x+1/11 + x+1/12 = x+1/13 + x+1/14
x+4/2000 + x+3/2001 = x+2/2002 + x+1/2003
TFM SỐ HỮU TỶ X:
a) X+1/10 + X+1/11 + X+1/12 =X+1/13 + X+1/14
b) X+4/2000 + X+3/2001 = X+2/2002+ X+1/2003
Tìm x, biết :
a) x+1/10 + x+1/11 + x+1/12 = x+1/13 + x+1/14
b) x+3/2000 + x+3/2001 = x+2/2002 + x+2/2003
1:x+4/2000+ x+3/2001= x+2/2002+ x+1/2003
2:7x(X-1)+2Xx(1-X)=0
3:11/12-(2/5+x)=2/3
4:A=3x+8xy+3y với x+y=4/3, x.y=-2
