Question

X-2,5=1/3+2/3xX

Answer 1

\(x-2.5=\frac{1}{3}+\frac{2x}{3}\)

\(\Leftrightarrow\frac{3\left(x-2,5\right)}{3}=\frac{2x+1}{3}\)

\(\Leftrightarrow3x-7,5=2x+1\)

\(\Leftrightarrow x=8,5\)

Answer 2

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

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

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

\(\frac{1}{3}x=\frac{17}{6}\)

\(x=\frac{17}{2}\)
