Question

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

Tìm x hộ mình với ạ. Trình bày bày giải luôn ạ. Thanks <3

Answer 1

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

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

\(\Rightarrow\frac{x}{4}=\frac{3}{5}\)

=> 5x = 12

=> x= 12/5

Answer 2

bn luân sai r 

Answer 3

\(\frac{x}{2}-\frac{3}{5}-\frac{x}{4}=0\)

\(\frac{x\cdot20}{40}-\frac{24}{40}-\frac{x\cdot10}{4}=0\)

\(x\cdot20-24-x10=0\)

\(x\left(20-10\right)-24=0\)

\(x10-24=0\)

\(x10=-24\)

\(x=-24:10=-2.4\)

vậy x=-2.4
