Answer 1

$4 \frac{1}{2} - x = 2 \frac{1}{3}$

$\frac{4 \times 2 + 1}{2} - x = \frac{2 \times 3 + 1}{3}$

$\frac{8 + 1}{2} - x = \frac{6 + 1}{3}$

$\frac{9}{2} - x = \frac{7}{3} \: | \times 6$

$27 - 6x = 14$

$- 6x = 14 - 27$

$- 6x = - 13 \: | \times ( - 1)$

$6x = 13$

$x = \frac{13}{6} \: \in \: \mathbb{Q}$

Answer 2

$4 \frac{1}{2} - x = 2 \frac{1}{3} \\ \frac{9}{2} - x = \frac{7}{3} \\ - x = \frac{7}{3} - \frac{9}{2} \\ - x = - \frac{13}{6} | \times ( - 1) \\ x = \frac{13}{6}$
