Answer 2

$\large{\tt{Answer\ :}}$

√x + 7 + 2 = 4

√x + 9 = 4

√x = 4 - 9

√x = -5

Square both sides to find 'x' ;

(√x)² = (-5)²

x = 25

$\large{\tt{\underline{\text{Verification\ :}}}}$

√x + 7 + 2 = 4

Put x = 25

√25 + 9 = 4

-5 + 9 = 4

4 = 4

$\underline{\text{Hence,\ Verified..!}}$

So, the value of x is $\bf{25}$.
