x/6=3/5+(-17/30)
x/6=18/30+(-17/30)
x/6=1/30
x=1/30.6
x=1/5
x/6=3/5+(-17/30)
x/6=18/30+(-17/30)
x/6=1/30
x=1/30.6
x=1/5
\(\frac{x}{5}=\frac{5}{6}+\frac{-19}{30}\)
\(x=\frac{1}{2}+\frac{-2}{3}\)
\(\frac{x}{30}=\frac{3}{5}+\frac{7}{30}\)
Đề bài: Tìm x biết:
Tìm x:
\(-\frac{5}{17}+\frac{3}{17}\le\frac{x}{17}\le\frac{13}{17}+-\frac{11}{17}\)
\(\frac{5}{6}+-\frac{7}{8}\le\frac{x}{24}\le-\frac{5}{12}+\frac{5}{8}\)
\(\frac{8}{17}+\frac{5}{17}< \frac{x}{17}< \frac{6}{17}+\frac{9}{17}\)
\(-\frac{6}{7}+\frac{3}{35}< \frac{x}{35}\le-\frac{2}{5}+\frac{3}{7}\)
ai nhanh và đúng mk tick
tìm x , y biết
a, \(\frac{4}{x}+\frac{y}{3}=\frac{5}{6}\)
b, \(\frac{5}{x}-\frac{y}{3}=\frac{1}{6}\)
c, \(\frac{x}{6}-\frac{2}{y}=\frac{1}{30}\)
Tìm x biết
\(5\frac{8}{17}:x+\frac{-4}{17}:x+3\frac{1}{7}:17\frac{1}{3}=\frac{4}{11}\)
Tìm x:
\(\frac{\left(13\frac{2}{9}-15\frac{2}{3}\right)\cdot\left(30^2-5^4\right)}{\left(18\frac{3}{7}-17\frac{1}{4}\right)\cdot\left(25-12\cdot5^2\right)}\cdot x=\frac{\frac{2}{11}+\frac{3}{13}+\frac{4}{15}+\frac{5}{17}}{4\frac{1}{11}+\frac{5}{13}+\frac{9}{15}+\frac{13}{17}}\)
Tìm x biết:
a) \(\frac{-2}{3}.x+\frac{1}{5}=\frac{3}{10}\)
b) (\(50\%.x+2\frac{1}{4}\)).\(\frac{-2}{3}=\frac{17}{6}\)
Tìm x , biết
a) x . \(3\frac{1}{4}\)+( \(-\frac{7}{6}\)) .x - \(1\frac{2}{3}\)= \(\frac{5}{12}\)
b) \(5\frac{8}{17}\): x + (\(-\frac{4}{17}\)) : x + \(3\frac{1}{7}\):\(17\frac{1}{3}\)= \(\frac{4}{11}\)
(Trình bày cách tìm x ra :>)
bài 1 : tìm x, biết
1) \(x+\frac{7}{12}=\frac{17}{18}-\frac{1}{9}\) 2) \(\frac{29}{30}-\left(\frac{13}{23}+x\right)=\frac{7}{69}\)
bài 2 : tìm x thuộc Z , biết
1) \(\frac{-5}{6}.\frac{120}{25}< x< \frac{-7}{15}.\frac{9}{14}\) 2) \(\left(\frac{-5}{3}\right)^3< x< \frac{-24}{25}.\frac{-5}{6}\)
Tìm x, biết:
\(1\frac{3}{5}+\left(\frac{\frac{2}{7}+\frac{2}{17}+\frac{2}{37}}{\frac{5}{7}+\frac{5}{17}+\frac{5}{37}}\right).x=\frac{16}{5}\)
