Answer 1

✓|+x/144=13/12

=} |+x/144=169/144

=}144 +x/144=169/144

144 will be cancelled by the other

=}144+x=169

=}x=169-144

=}x=25

Answer 2

Answer:-

$\mathsf{ \sqrt{1} + \frac{x}{144} = \frac{13}{12} }$

$\mathsf{1 + \frac{x}{144} = { (\frac{13}{12}) }^{2} }$

$\mathsf{1 + \frac{x}{144} = \frac{169}{144} }$

$\mathsf{ \frac{144 + x}{144} = \frac{169}{144} }$

[ 144 gets cancelled ]

$\mathsf{144 + x = 169}$

$\mathsf{x = 169 - 144}$

$\mathsf{x = 25}$
