Answer 2

Solution :

Equation that we have with us,

$\implies$ $\huge{\boxed{\sf{ \sqrt{x - 9} = 4}}}$

On squaring both sides of the equation:

$\implies$ $\sf{(\sqrt{x - 9})^{2} = 4 ^{2}}$

$\implies$ $\sf{x - 9 = 4 \times 4}$

$\implies$ $\sf{x - 9 = 16}$

$\implies$ $\sf{x = 16 + 9}$

$\implies$ $\sf{x = 25}$

Hence,

The value of 'x' is 25.
