Xx2/3+Xx73=11/4

Answer 1

[Dora]

\(x \times \dfrac{2}{3}+x\times\dfrac{7}{3}=\dfrac{11}{4}\)

\(x\times(\dfrac{2}{3}+\dfrac{7}{3})=\dfrac{11}{4}\)

\(x\times3=\dfrac{11}{4}\))

\(x=\dfrac{11}{4}:3 =\dfrac{11}{12}\)

Answer 2

[tueanh2k3]

$x\times \genfrac{}{}{0ex}{}{2}{3}+x\times \genfrac{}{}{0ex}{}{7}{3}=\genfrac{}{}{0ex}{}{11}{4}$

$x\times (\genfrac{}{}{0ex}{}{2}{3}+\genfrac{}{}{0ex}{}{7}{3})=\genfrac{}{}{0ex}{}{11}{4}$

$x\times 3=\genfrac{}{}{0ex}{}{11}{4}$)

$x=\genfrac{}{}{0ex}{}{11}{4}:3=\genfrac{}{}{0ex}{}{11}{12}$
