` 5/8 -x = 7/6`
`=> x= 5/8 -7/6`
`=>x= 30/48 - 56/48`
`=>x=-26/48`
`=>x=-13/24`

`1/6 + 1/5 :x =-7 /18`
`=> 1/5 :x =-7 /18 -1/6`
`=> 1/5 :x =-7 /18- 3/18`
`=> 1/5 :x =-5/9`
`=>x= 1/5 : (-5/9)`
`=>x= 1/5 xx (-9/5)`
`=>x=-9/25`
a: x=5/8-7/6=15/24-28/24=-13/24
b: =>1/5:x=-7/18-1/6=-7/18-3/18=-10/18=-5/9
=>x=-1/5:5/9=-9/25
X + X x \(\dfrac{1}{3}\) + \(\dfrac{5}{18}\) = \(\dfrac{7}{6}\)
X x \(\dfrac{4}{3}\) = \(\dfrac{7}{6}-\dfrac{5}{18}\)
X x \(\dfrac{4}{3}\) = \(\dfrac{8}{9}\)
X = \(\dfrac{8}{9}:\dfrac{4}{3}=\dfrac{2}{3}\)
\(x\cdot\left(\dfrac{1}{3}+1\right)=\dfrac{21}{18}-\dfrac{5}{18}=\dfrac{16}{18}=\dfrac{8}{9}\)
\(x=\dfrac{8}{9}:\dfrac{4}{3}=\dfrac{8}{9}\cdot\dfrac{3}{4}=\dfrac{4\cdot2\cdot3}{3\cdot3\cdot4}=\dfrac{2}{3}\)
\(\frac{1.5.18+2.10.36+3.15.54}{1.3.9+2.6.18+3.9.27}=\frac{1.5.18.\left(1+2.2.2+3.3.3\right)}{1.3.9.\left(1+2.2.2+3.3.3\right)}\)
\(=\frac{1.5.18}{1.3.9}=\frac{10}{3}\)
\(\frac{5}{6}-\left(x+\frac{1}{18}\right)=0\)
\(\frac{5}{6}-x=\frac{1}{18}\)
\(x=\frac{5}{6}-\frac{1}{18}\)
\(x=\frac{7}{9}\)
\(\frac{5}{6}\)- (x+\(\frac{1}{18}\)) =0
\(\frac{5}{6}\)-x =0
x =\(\frac{5}{6}\)-0
x =\(\frac{5}{6}\)- \(\frac{1}{18}\)
x =\(\frac{14}{18}\)= \(\frac{7}{9}\)

Tìm x,biết :1/6+ -5/7:x= - 7/18
=> -5/7 : x = -7/18 - 1/6
=> -5/7 : x = -5/9
=> x = -5/9 : -5/7 = 7/9
\(\dfrac{3}{2}+\dfrac{-1}{3}< \dfrac{x}{6}< \dfrac{1}{9}+\dfrac{31}{18}\)
\(\dfrac{7}{6}< \dfrac{x}{6}< \dfrac{11}{6}\)
\(=>x=8,9,10\)
1: =>x/5=6/5
=>x=6
2: =>x^2=36
=>x=6 hoặc x=-6
3: =>x-5/2=3+1/6=19/6
=>x=19/6+5/2=19/6+15/6=34/6=17/3
4: =>x=1/2:2/5=1/2*5/2=5/4
