$\Large \fbox \red {Question \: :}$

Find the value of

$3 \sqrt{4x} - 7 - 5 = 0$

$\Large \fbox \red {Answer \: :}$

$= > 3 \sqrt{4x} - 7 - 5 = 0$

$3 \sqrt{4} \sqrt{x} - 12 = 0$

$3 \times 2 \sqrt{x} - 12 = 0$

$6 \sqrt{x} = 12$

$\sqrt{x} = 12 \div 6$

$\sqrt{x} = 2$

$x = {2}^{2}$

$x = 4$

$\therefore$ The answer is 4.
