Answer 1

$9-6\sqrt{x-4}+4=0\\ \\ 6\sqrt{x-4}=13\\ \\ \sqrt{x-4}=\frac{13}{6}\\ \\ x-4=\frac{169}{36}\\ \\ x=4+\frac{169}{36}\\ \\ x=\frac{313}{36}$

Answer 2

Oie, Td Bom?!

$9 - 6 \sqrt{x - 4} + 4 = 0$

$13 - 6 \sqrt{x - 4} = 0$

$- 6 \sqrt{x - 4} = - 13$

$\sqrt{x - 4} = - 13 \div ( - 6)$

$\sqrt{x - 4} = 3 \div 16$

$\sqrt{x - 4} = \frac{169}{36}$

$x - 4 = \frac{169}{36}$

$x = \frac{169}{36} + 4$

$x = \frac{313}{36}$
