Question

1.Tìm \(x\):

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

Answer 1

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

\(\frac{1}{2}\times x=\frac{5}{2}-\frac{2}{3}\)

\(\frac{1}{2}\times x=\frac{11}{6}\)

\(x=\frac{11}{6}\div\frac{1}{2}\)

\(x=\frac{11}{3}\)

Answer 2

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

\(\frac{1}{2}x=\frac{5}{2}-\frac{2}{3}=\frac{11}{6}\)

\(x=\frac{11}{6}\div\frac{1}{2}\)

\(x=\frac{11}{3}\)
