Question

0,75+\(\dfrac{2}{5}x\) = \(\sqrt{\dfrac{25}{4}}\) - \(\dfrac{1}{4}\)

Answer 1

\(0,75+\dfrac{2}{5}x=\sqrt{\dfrac{25}{4}}-\dfrac{1}{4}\)

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

\(\dfrac{2}{5}x=\dfrac{5}{2}-1\)

\(\dfrac{2}{5}x=\dfrac{3}{2}\)

\(x=\dfrac{3}{2}:\dfrac{2}{5}\)

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