Verified answer

1)

[tex] \frac{52}{63} - \frac{x}{63} = \frac{25}{63} [/tex]

[tex]52 - x = 25[/tex]

[tex] - x = 25 - 52[/tex]

[tex] - x = - 27[/tex]

[tex]x = 27[/tex]

2)

[tex] \frac{x}{38} - \frac{14}{38} = \frac{23}{38} [/tex]

[tex]x - 14 = 23[/tex]

[tex]x = 23 + 14[/tex]

[tex]x = 37[/tex]
