Answer:
x = 16
Step-by-step explanation:
7 = 3 + sqrt(x)
Subtract 3 from each side
7-3 = 3-3+sqrt(x)
4 = sqrt(x)
square each side
4^2 = (sqrt(x))^2
16 =x
[tex]x=16[/tex]
Step 1: Subtract 3 from both sides
[tex]7-3=3+\sqrt{x} -3[/tex]
[tex]4=\sqrt{x}[/tex]
Step 2: Square both sides
[tex]4^2=(\sqrt{x}) ^2[/tex]
[tex]16=x[/tex]
Answer: [tex]x=16[/tex]
