( 5,5.x - 44 : - 3/2 = 30
=> 5,5.x - 44 = 30. - 3/2
5,5.x - 44 =- 45
=> 5,5.x = ( - 45 )+44
5,5 .x = - 1
x =- 1 : 5,5
x =- 2/11
(5,5x-44):(-\(\frac{3}{2}\))=30
5,5x-44 =30.(\(-\frac{3}{2}\))=-45
5,5x =-45+44=-1
x =-1:5,5=\(-\frac{2}{11}\)
( 5,5.x - 44 : - 3/2 = 30
=> 5,5.x - 44 = 30. - 3/2
5,5.x - 44 =- 45

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 = \(\frac{-1}{28}\)
Tìm x, biết: 5 , 5 x = 13 15
Tìm \(x\) :
\(a.1\dfrac{2}{4}x-1\dfrac{2}{3}=2\dfrac{3}{5}\) \(b.0,5x-\dfrac{2}{3}x=\dfrac{7}{12}\) \(c.5,5x=\dfrac{1}{2}\)
Tìm x biết
0,5x - 2/3x = 7/12
5,5x = 13/15
(3x/7 +1) : (-4)= -1/28
Tìm x, biết : \(\left[\frac{45\frac{10}{63}-44\frac{25}{84}}{\left(2\frac{1}{3}-1\frac{1}{9}\right):4-\frac{3}{4}}:31\right].x=-\frac{1}{16}\)
Tìm x biết
8) ( 13/ 10 x- 15) . -5/ 14= 3
10) ( 5,5 x- 44) : ( -3/ 2) = 30
11/ 14: ( 2x+ 5/7) = 11/ 18
1.Tìm số nguyên x biết
\(\frac{x-2}{27}+\frac{x-3}{26}+\frac{x-4}{25}+\frac{x-5}{24}+\frac{x-44}{5}=1\)
2.tìm các số nguyên x, y thỏa mãn
\(\frac{x}{2}+\frac{x}{y}-\frac{3}{2}=\frac{10}{y}\)
Mình đang cần gấp! Cảm ơn nhiều
Tìm x, biết :
\(a.0,5x-\frac{2}{3}x=\frac{7}{12}\) \(b.x:4\frac{1}{3}=-2,5\)
\(c.5,5x=\frac{13}{15}\) \(d.\left(\frac{3x}{7}+1\right):\left(-4\right)=-\frac{1}{28}\)
\(\frac{x}{5}=\frac{5}{6}+\frac{-19}{30}\)
\(x=\frac{1}{2}+\frac{-2}{3}\)
\(\frac{x}{30}=\frac{3}{5}+\frac{7}{30}\)
