Question

Tìm x:

\(\frac{3}{4}x+\frac{2}{5}x-\frac{5}{3}=-2\)

Answer 1

\(\frac{3}{4}x+\frac{2}{5}x-\frac{5}{3}=-2\)

\(\Leftrightarrow\)\(\frac{23}{20}x=-\frac{1}{3}\)

\(\Leftrightarrow\)\(x=-\frac{20}{69}\)

Answer 2

\(\frac{3}{4}x+\frac{2}{5}x-\frac{5}{3}=-2\)

\(x\left(\frac{3}{4}+\frac{2}{5}\right)-\frac{5}{3}=-2\)

\(x\frac{23}{20}=-2+\frac{5}{3}\)

\(x\frac{23}{20}=-\frac{1}{3}\)

\(x=-\frac{20}{69}\)
