Question

\(\dfrac{3}{2}\) + ( \(\dfrac{4}{5}\) : X - \(\dfrac{1}{20}\) ) = 4

Answer 1

\(\dfrac{3}{2}+\left(\dfrac{4}{5}:x-\dfrac{1}{2}\right)=4\)

\(\dfrac{3}{2}+\dfrac{4}{5}:x-\dfrac{1}{2}=4\)

\(\left(\dfrac{3}{2}-\dfrac{1}{2}\right)+\dfrac{4}{5}:x=4\)

\(\dfrac{2}{2}+\dfrac{4}{5}:x=4\)

\(1+\dfrac{4}{5}:x=4\)

\(\dfrac{4}{5}:x=4-1\)

\(\dfrac{4}{5}:x=3\)

\(x=\dfrac{4}{5}:3\)

\(x=\dfrac{4}{15}\)
