Question

3/5x-1/2x=-7/20

Answer 1

\(\frac{3}{5}x-\frac{1}{2}x=-\frac{7}{20}\)

\(\Leftrightarrow\left(\frac{3}{5}-\frac{1}{2}\right)x=-\frac{7}{20}\)

\(\frac{1}{10}x=-\frac{7}{20}\)

\(x=-\frac{7}{20}:\frac{1}{10}\)

\(x=-\frac{7}{2}\)

Answer 2

\(\frac{3}{5}x-\frac{1}{2}x=-\frac{7}{20}\)

\(\leftrightarrow\left(\frac{3}{5}-\frac{1}{2}\right)x=-\frac{7}{20}\)

\(\leftrightarrow\frac{1}{10}x=-\frac{7}{20}\)

\(\leftrightarrow x=-\frac{7}{20}:\frac{1}{10}=-\frac{7}{2}\)

Answer 3

\(\Leftrightarrow\left(\frac{3}{5}-\frac{1}{2}\right)x=\frac{-7}{20}\)

\(\frac{1}{10}x=\frac{-7}{20}\)

\(\Rightarrow x=\frac{-7}{20}:\frac{1}{10}\)

\(x=\frac{-7}{2}\)
