Let x = the number
So, the given situation can be expressed as:
[tex]\frac{2}{7}x=30-x[/tex]Then, solve for x:
[tex]\begin{gathered} \frac{2}{7}x+x=30-x+x \\ \frac{9}{7}x=30 \\ \frac{7}{9}\cdot\frac{9}{7}x=30\cdot\frac{7}{9} \\ x=\frac{210}{9}=\frac{70}{3} \end{gathered}[/tex]Answer: the number is 70/3
