Question

Which equation is equivalent to sqrt x +11=15

Answer 1

Answer: sqrt(x) - 11 = 15

Explanation:

Answer 2

x=16

Explanation:

We are given that

`\sqrtx+11=15`

we have to solve this equation for x

in order to do that we need to isolate x first

hence

subtracting 11 from both sides we get

`\sqrtx+11-11=15-11`

`\sqrtx=4`

Now we square on both sides we get

`(\sqrtx)^2=4^2`

`x=4 * 4`

`x=16`

hence x =16
