Tìm x, biết:
a, \(\left(2\dfrac{3}{4}-1\dfrac{4}{5}\right)x=1\)
b, \(x^2-9\) \(3-5x=0\)
c, \(\left|3x-1\right|+2\dfrac{3}{4}=3\dfrac{1}{16}\)
\(\dfrac{x}{5}=\dfrac{3}{y}\)Tìm số nguyên x biết
Tìm số nguyên x, y biết:
a, \(\dfrac{-1}{5}\)≤ \(\dfrac{x}{8}\)≤ \(\dfrac{1}{4}\)
b, \(\dfrac{4}{x-6}\)= \(\dfrac{y}{24}\)= \(\dfrac{-12}{18}\)
c, \(\dfrac{x+46}{20}\)=x \(\dfrac{2}{5}\)
tìm x biết
a, ( 3\(\dfrac{1}{3}\) - x) 1\(\dfrac{1}{6}\) = \(\dfrac{7}{24}\) b, ( 4,5 - 2x ) : \(\dfrac{3}{4}\) = 1\(\dfrac{1}{3}\)
a, \(\dfrac{x-2}{15}+\dfrac{x-3}{14}+\dfrac{x-4}{13}+\dfrac{x-5}{12}=4\)
b, \(\dfrac{x+1}{19}+\dfrac{x+2}{18}+\dfrac{x+3}{17}+...+\dfrac{x+18}{2}+18=0\)
Cảm ơn khi đã giúp mình
Tìm x biết:
(\(\dfrac{1}{8}+2\dfrac{5}{4}-2,75\))x-7=(\(\dfrac{3}{2}+0,65+\dfrac{7}{200}\));0,07
Tìm x
a) \(\left[\left(6\dfrac{3}{7}-\dfrac{0,75.x-2}{0,35}\right).2,8+1,75\right]:0,05=2,35\)
b) \(\dfrac{3}{5}-\dfrac{2}{7}< \dfrac{2}{3}.x+\dfrac{3}{4}< \dfrac{1}{2}+\dfrac{7}{9}\)
a) \(\dfrac{1}{2.3}x+\dfrac{1}{3.4}x+\dfrac{1}{4.5}x+....+\dfrac{1}{49.50}x=1\)
b) \(\dfrac{1}{5}+\dfrac{2}{11}< \dfrac{x}{55}< \dfrac{2}{5}+\dfrac{1}{55}\)
Tìm x:
\(\dfrac{1}{6}\)(x + \(\dfrac{3}{2}\)) - \(\dfrac{2}{3}\)x = \(\dfrac{5}{4}\)
