Question

`7=3+√(x)`

Answer 1

`x=16`

Explanation:

Step 1: Subtract 3 from both sides

`7-3=3+√(x) -3`

`4=√(x)`

Step 2: Square both sides

`4^2=(√(x)) ^2`

`16=x`

Answer:
`x=16`

Answer 2

x = 16

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
