Question

a) -1/2 + 5x = 3/4 : 3/5

Answer 1

 -1/2 + 5x = 5/4

5x = 5/4 - (-1)/2

5x = 7/4

x = 7/4 : 5

x = 7/20

Answer 2

`-1/2 + 5x = 3/4 : 3/5`

`5x = 5/4 - (-1/2)`

`5x = 7/4`

`x = 7/4 : 5`

`x = 7/20`

Answer 3

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

    \(\dfrac{-1}{2}+5x=\dfrac{5}{4}\)

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

              \(5x=\dfrac{7}{4}\)

                \(x=\dfrac{7}{4}:5\)

                 \(x=\dfrac{7}{20}\)

Answer 4

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

\(\Leftrightarrow5x=\dfrac{5}{4}-\dfrac{-1}{2}\)

\(\Leftrightarrow5x=\dfrac{7}{4}\)

\(\Leftrightarrow x=\dfrac{7}{4}:5\)

\(\Leftrightarrow x=\dfrac{7}{4}\times\dfrac{1}{5}\)

\(\Leftrightarrow x=\dfrac{7}{20}\)

Answer 5

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

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

          \(5x=\dfrac{5}{4}-\left(\dfrac{-1}{2}\right)=\dfrac{7}{4}\)

           \(x=\dfrac{7}{4}:5=\dfrac{7}{20}\)
