$\frac{-1}{3}$ × x = $\frac{7}{6}$ – $\frac{3}{2}$ × x ⇒ $\frac{-1}{3}$ × x – $\frac{3}{2}$ × x = $\frac{7}{6}$ x × ( $\frac{-1}{3}$ – $\frac{3}{2}$ = $\frac{7}{6}$ x × ($\frac{-11}{6}$) = $\frac{7}{6}$ x = $\frac{7}{6}$ ÷ ($\frac{-11}{6}$) x = $\frac{-7}{11}$. Trả lời
$\frac{-1}{3}$ × x = $\frac{7}{6}$ – $\frac{3}{2}$ × x
⇒ $\frac{-1}{3}$ × x – $\frac{3}{2}$ × x = $\frac{7}{6}$
x × ( $\frac{-1}{3}$ – $\frac{3}{2}$ = $\frac{7}{6}$
x × ($\frac{-11}{6}$) = $\frac{7}{6}$
x = $\frac{7}{6}$ ÷ ($\frac{-11}{6}$)
x = $\frac{-7}{11}$.
`(-1x)/3=7/6-(3x)/2`
`⇔-2x=7-9x`
`⇔7x=7`
`⇔x=7:7=1`
