Question

(-0,75x + 5/2) x 7/4 -(-1/3) = -5/7

Answer 1

\(\left(-0,75x+\frac{5}{2}\right).\frac{7}{4}-\left(\frac{-1}{3}\right)=\frac{-5}{7}\)

\(\left(-0,75x+\frac{5}{2}\right).\frac{7}{4}=\frac{-5}{7}+\left(\frac{-1}{3}\right)\)

\(\left(-0,75x+\frac{5}{2}\right).\frac{7}{4}=\frac{-22}{21}\)

\(-0,75x+\frac{5}{2}=\frac{-22}{21}:\frac{7}{4}\)

\(-0,75x+\frac{5}{2}=\frac{-88}{147}\)

\(-0,75x=\frac{-88}{147}-\frac{5}{2}\)

\(-0,75x=\frac{-911}{294}\)

\(x=\frac{-911}{294}:\left(-0,75\right)\)

\(x=\frac{1822}{441}\)
