Giúp mỉnh nhanh nha

Answer 1

giải:

\(\left(x\cdot\frac{1}{4}-\frac{22}{3}\right)\cdot\frac{21}{3}=\frac{15}{8}\)

\(x\cdot\frac{1}{4}-\frac{22}{3}=\frac{15}{8}:\frac{21}{3}\)

\(x\cdot\frac{1}{4}-\frac{22}{3}=\frac{15}{56}\)

\(x\cdot\frac{1}{4}=\frac{15}{56}+\frac{22}{3}\)

\(x\cdot\frac{1}{4}=\frac{1277}{168}\)

\(x=\frac{1277}{168}:\frac{1}{4}\)

\(x=\frac{1277}{42}\)
