Answer 2

Answer:

x = -143/81

Step-by-step explanation:

Given that:

$9\sqrt{x + 3} - 3 = 7$

By simplifying:

$9\sqrt{x + 3} = 7 + 3\\ 9\sqrt{x + 3} = 10$

Dividing both sides by 9 we get:

$\sqrt{x + 3} = 10/9$

Squaring both sides we get:

x + 3 = 100/81

Subtracting 3 from both sides we get:

x = 100/81 - 3

x = 100 - 243/ 81

x = -143/81

i hope it will help you!
