Answer:
Step-by-step explanation:
[tex]5 \sqrt{x} -6=-20[/tex]
1. You divide 5 by both sides, which will give you [tex]\sqrt{x-6}=-4[/tex]
2. You then square both sides of the equation, which will give you [tex]x-6=16[/tex]
3. Since the equation is now one-step, you then do GEMDAS and you will get x=22
