Question

2 1/5+ 3/5x= 3/4

Answer 1

\(2\frac{1}{5}+\frac{3}{5}x=\frac{3}{4}\)

\(\Rightarrow\frac{11}{5}+\frac{3}{5}x=\frac{3}{4}\Rightarrow\frac{3}{5}x=\frac{3}{4}-\frac{11}{5}=-\frac{29}{20}\Rightarrow x=-\frac{29}{20}:\frac{3}{5}=-\frac{29}{12}\)

Vậy x=-29/12

Answer 2

3/5x=3/4-21/5

3/5x=-69/20

69/115x=69/20

115x=20

x=20:115

x=4/23

Answer 3

-29/12 nha bn

Answer 4

3/5x=3/4-21/5

3/5x=-69/20

x=-69/20:3/5

x=-23/4

Answer 5

\(2\frac{1}{5}+\frac{3}{5}x=\frac{3}{4}\)

\(\frac{11}{5}+\frac{3}{5}x=\frac{3}{4}\)

\(\frac{3}{5}x=\frac{3}{4}-\frac{11}{5}\)

\(\frac{3}{5}x=\frac{15}{20}-\frac{44}{20}\)

\(\frac{3}{5}x=\frac{-29}{20}\)

\(x=\frac{-29}{20}:\frac{3}{5}\)

\(x=\frac{-29}{20}\)x\(\frac{5}{3}\)

\(x=\frac{-29x5}{20x3}\)

\(x=\frac{-29}{12}\)
