Answer:
[tex]x=12[/tex] is the only solution
Step-by-step explanation:
Assuming we want to solve the radical equation: [tex]\sqrt{x+4}-3=1[/tex]
We add 3 to both sides to get: [tex]\sqrt{x+4}=1+3[/tex]
Simplify to get:
[tex]\sqrt{x+4}=4[/tex]
Square both sides to obtain:
[tex](\sqrt{x+4})^2=4^2\\x+4=16\\\implies x=16-4\\\implies x=12[/tex]
