Question

$7=3+\sqrt{x}$

Answer 1

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

Answer 2

Answer:

$x=16$

Step-by-step explanation:

Step 1:  Subtract 3 from both sides

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

$4=\sqrt{x}$

Step 2:  Square both sides

$4^2=(\sqrt{x}) ^2$

$16=x$

Answer:  $x=16$
