It is given that \((\frac {x}{3}+1, \frac {y-2}{3}) = (\frac {5}{3}, \frac {1}{3})\).
Since the ordered pairs are equal, the corresponding elements will also be equal.
\((\frac {x}{3}+1, \frac {y-2}{3}) = (\frac {5}{3}, \frac {1}{3})\)
Therefore,
\(\frac {x}{3}+1=\frac {5}{3}\)
⇒ \(\frac{x}{3} = \frac{5}{3} -1,\frac{y-2}{3} = \frac{1}{3}\)
⇒\(\frac{x}{3} = \frac{2}{3}, y = \frac{1}{3}+\frac{2}{3}\)
⇒ x=2, y=1
Figures 9.20(a) and (b) refer to the steady flow of a (non-viscous) liquid. Which of the two figures is incorrect ? Why ?
