Answer:

y = 20

Step-by-step explanation:

$9 - \sqrt{y - 4} = 5$

<h3>i) move 9 to the right-hand side and change its sign</h3>

$- \sqrt{y - 4} = 5 - 9$

<h3>ii) calculate the difference</h3>

$- \sqrt{ y - 4} = - 4$

<h3>iii) change the signs on both sides of the equation</h3>

$\sqrt{y - 4} = 4$

<h3>iv) square both sides of the equation</h3>

$( \sqrt{y - 4} ) {}^{2} = 4 {}^{2}$

$y - 4 = 4 {}^{2}$

$y - 4 = 16$

<h3>v) move -4 to the right-hand side and change its sign</h3>

$y = 16 + 4$

<h3>vi) add the numbers</h3>

$y = 20$
