Answer 3

\(x-\left(\frac{50x}{100}+\frac{25x}{200}\right)=\frac{45}{4}\)

\(x-\left(\frac{1x}{2}+\frac{1x}{8}\right)=\frac{45}{4}\)

\(x-\left(\frac{4x}{8}+\frac{1x}{8}\right)=\frac{45}{4}\)

\(x-\frac{5x}{8}=\frac{45}{4}\)

\(\frac{8x}{8}-\frac{5x}{8}=\frac{45}{4}\)

\(\frac{3x}{8}=\frac{45}{4}\Leftrightarrow x=\frac{45}{4}:\frac{3}{8}=30\)

Vậy \(x=30\)

Answer 4

\(\text{Giải :}\)

\(x-\left(\frac{50x}{100}+\frac{25x}{200}\right)=\frac{45}{4}\)

\(\Rightarrow x-\left(\frac{1x}{2}+\frac{1x}{8}\right)=\frac{45}{4}\)

\(\Rightarrow x-\left(\frac{4x}{8}+\frac{1x}{8}\right)=\frac{45}{4}\)

\(\Rightarrow x-\frac{5x}{8}=\frac{45}{4}\)

\(\Rightarrow\frac{8x}{8}-\frac{5x}{8}=\frac{45}{4}\)

\(\Rightarrow\frac{3x}{8}=\frac{45}{4}\)

\(\Rightarrow x=\frac{45}{4}:\frac{3}{8}=30\)
