Answer 1

\(=>x\left(\dfrac{1}{2}+\dfrac{2}{3}\right)=\dfrac{10}{3}+1=\dfrac{13}{3}\)

\(=>x=\dfrac{13}{3}:\left(\dfrac{1}{2}+\dfrac{2}{3}\right)=\dfrac{13}{3}:\dfrac{7}{6}=\dfrac{26}{7}\)

Answer 2

5/6x - 1 = 10/3

5/6x = 10/3 + 1 = 13/3

X = 13/3 : 5/6 = 26/5

Answer 3

\(\dfrac{1}{2}\times x+\dfrac{2}{3}\times x-1=3\dfrac{1}{3}\)

\(\Rightarrow x\left(\dfrac{1}{2}+\dfrac{2}{3}\right)=\dfrac{10}{3}+1\)

\(\Rightarrow\dfrac{7}{6}x=\dfrac{13}{3}\)

\(\Rightarrow x=\dfrac{13}{3}:\dfrac{7}{6}\)

\(\Rightarrow x=\dfrac{26}{7}\)

Answer 4

\(\dfrac{1}{2}\times x+\dfrac{2}{3}\times x-1=3\dfrac{1}{3}\)

\(\dfrac{1}{2}\times x+\dfrac{2}{3}\times x-1=\dfrac{10}{3}\)

\(\dfrac{1}{2}\times x+\dfrac{2}{3}\times x=\dfrac{10}{3}+1\)

\(\dfrac{1}{2}\times x+\dfrac{2}{3}\times x=\dfrac{13}{3}\)

\(\left(\dfrac{1}{2}+\dfrac{2}{3}\right)\times x=\dfrac{13}{3}\)

\(\dfrac{7}{6}\times x=\dfrac{13}{3}\)

   \(x=\dfrac{13}{3}:\dfrac{7}{6}\)

   \(x=\dfrac{26}{7}\)
