Answer 3

\(\left(x-\frac{1}{2}\right)\cdot\frac{5}{2}+\frac{1}{2}=\frac{7}{4}\)

=> \(\left(x-\frac{1}{2}\right)\cdot\frac{5}{2}=\frac{7}{4}-\frac{1}{2}\)

=> \(\left(x-\frac{1}{2}\right)\cdot\frac{5}{2}=\frac{7}{4}-\frac{2}{4}=\frac{5}{4}\)

=> \(\left(x-\frac{1}{2}\right)=\frac{5}{4}:\frac{5}{2}\)

=> \(\left(x-\frac{1}{2}\right)=\frac{5}{4}\cdot\frac{2}{5}=\frac{1}{2}\)

=> \(x=\frac{1}{2}+\frac{1}{2}=1\)

Vậy x = 1
