tìm x :
0,5x - 3/2x = 3\(0,5x-\frac{3}{2}x=\frac{2}{7}\)
TÌM X BIẾT
\(0,5x-75\%x=\left(\frac{1}{3}-1\right)^2\)
tìm x:
\(\left|x\right|-5\frac{3}{7}\times\left|x\right|-\frac{3}{4}=2\times\left|x\right|+\frac{-15}{2}\)
\(50\%+\frac{2}{3}x=x+4\)
\(0,5x-\frac{2}{3}\left(x+1\right)=\frac{-1}{12}\)
\(\frac{1}{2}\left(x-\frac{2}{3}\right)-\frac{2}{5}\left(2-x\right)=\frac{1}{9}\)
tìm x:
a,\(\frac{x}{2\times5}+\frac{x}{5\times8}+\frac{x}{8\times11}+\frac{x}{11\times14}=\frac{3}{7}\)
b, \(50\%+\frac{2}{3}x=x+4\)
c,\(0,5x-\frac{2}{3}\left(x+1\right)=\frac{-1}{12}\)
d,\(\frac{1}{2}\left(x-\frac{2}{3}\right)-\frac{2}{5}\left(2-x\right)=\frac{1}{9}\)
Tìm x:
A. 0,5x - \(\frac{1}{3}\) x =\(\frac{1}{3}\)
B. x: \(3\frac{1}{2}\) = -1,5
C. 1,5x = \(\frac{11}{5}\)
Bài 1: Tính:
\(\frac{1}{4}+\frac{7}{12}-\frac{6}{13}-\frac{7}{8}\)
Bài 2: Tìm x:
0,5x - \(\frac{2}{3}\)x = \(\frac{5}{12}\)
tìm x ,biết
a, 0,5x-2/3x=7/12
b, x : 4\(\frac{1}{3}\) = -2,5
c, 5,5x =13/15
d ,{\(\frac{3x}{7}\)+1} : -4 = \(\frac{-1}{28}\)
0,2:\(1\frac{1}{5}\)=2/3 : [6x +7]
\(3\frac{1}{3}\): 4,8 = 0,5x :7
[31/30-26/25] . -36/35 < x<[51/56 +8/21 + 1/3 ] . 8/3
1/3 +3/35 < x/210 < 4/7 +3/5 + 1/3 tìm x
Tìm x
x + \(\frac{30}{100}\)x = -1,3
( \(\frac{3}{7}x+1\) ) : (-4) = \(\frac{-1}{28}\)
0,5x - \(\frac{2}{3}x\) = \(\frac{7}{12}\)
