Answer 3

a)\(x=\dfrac{5}{4}-\dfrac{2}{3}=\dfrac{7}{12}\)

b)\(x=\dfrac{17}{12}:\dfrac{1}{2}-\dfrac{3}{10}=\dfrac{17}{6}-\dfrac{3}{10}=\dfrac{38}{15}\)

Answer 4

a) \(x=\dfrac{5}{4}-\dfrac{2}{3}\)

\(x=\dfrac{23}{12}\)

b) \(\left(x+\dfrac{3}{10}\right)=\dfrac{17}{12}:\dfrac{1}{2}\)

\(\left(x+\dfrac{3}{10}\right)=\dfrac{17}{12}\times\dfrac{2}{1}\)

\(\left(x+\dfrac{3}{10}\right)=\dfrac{17}{6}\)

\(x=\dfrac{17}{6}-\dfrac{3}{10}\)

\(x=\dfrac{38}{15}\)
