Answer 2

The equation is equivalent to the given equation is $\sqrt{x} =15-11$.

Given that

Equation; $\rm \sqrt{x} +11 =15$

We have to determine

Which equation is equivalent to the given equation?

According to the question

To determine the equation is equivalent to the given equation following all the steps given below.

Equation; $\rm \sqrt{x} +11 =15$

Then,

Subtracting 11 from both sides.

$\rm \sqrt{x} +11 =15\\\\\rm \sqrt{x} +11-11 =15-11\\\\\rm \sqrt{x} =15-11$

Hence, the equation is equivalent to the given equation is $\sqrt{x} =15-11$.
