Question

\(a,\frac{2}{3}+\frac{3}{4}\div x=\frac{-1}{6}\)

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

 

Answer 1

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

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

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

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

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

Answer 2

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

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

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

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

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