\(\frac{-1}{3}\le x\le\frac{-2}{7}\Rightarrow\frac{-7}{21}\le x\le\frac{-6}{21}\Rightarrow x\varepsilon\left\{\frac{-7}{21};\frac{-6}{21}\right\}\)
tim x , biet :
\(\frac{-1}{3}\le x\le\frac{-2}{7}\)
giup mk nha cac bn,lam on
Tim x biet :
a, \(4\frac{1}{3}\left(\frac{1}{6}-\frac{1}{2}\right)\le x\le\frac{2}{3}\left(\frac{1}{2}-\frac{1}{3}-\frac{3}{4}\right)\) x thuoc Z
b , \(|x-3|+1=x\)
tim so nguyen x:
1+\(\frac{1}{3}+\frac{1}{6}+...+\frac{1}{x\left(x+1\right):2}=1\frac{1991}{1993}\)
giup le nha! love
tim so tu nhien x,biet
a, 2x+3x=1505
b,1+35+...+x=3200(xla so le)
c,(x+1)+(X+2)+(x+3)+....+(x+100)=5750
giup minh voi mai minh can roi
cam on cac ban nhieu lam
Tìm x:
\(-\frac{5}{17}+\frac{3}{17}\le\frac{x}{17}\le\frac{13}{17}+-\frac{11}{17}\)
\(\frac{5}{6}+-\frac{7}{8}\le\frac{x}{24}\le-\frac{5}{12}+\frac{5}{8}\)

\(-\frac{6}{7}+\frac{3}{35}< \frac{x}{35}\le-\frac{2}{5}+\frac{3}{7}\)
ai nhanh và đúng mk tick
cho x,y,z là các số thực khác 0, thõa mãn các điều kiện 1 \(\le\) x \(\le\) \(\frac{7}{3};\frac{1}{2}\le y\le\frac{7}{6};\frac{1}{3}\le z\le\frac{7}{9}\)
mn giup minh voi
tim so tu nhien x biet
a, 0.(5-x)=0
b,1+35+.......+x = 3200 ( x la so le )
c, (x+1)+(x+2)+(x+3)+....+(x+100)
d 2x+3x=1505
cam on mn nhieu
Tìm x:
\(\frac{4}{3}.\left(\frac{1}{6}-\frac{1}{2}\right)\le x\le\frac{2}{3}.\left(\frac{-1}{6}+\frac{3}{4}\right)\)
BN NÀO GIẢI TỪNG BƯỚC RA GIÚP MK , MK SẼ TICK.
tim x thuoc Z biet \(\frac{x}{4}\)= \(\frac{18}{x+1}\)
giup voi
