Answer 2

$x = 126$ is the solution for equation $\sqrt{2x+4}=16$.

What is equation?

An equation is a mathematical statement that is made up of two expressions connected by an equal sign.

Given equation

$\sqrt{2x+4}=16$

Squaring on both sides

$(\sqrt{2x+4} )^{2} =16^{2}$

⇒ $2x+4=256$

Subtract 4 on both sides.

⇒ $2x +4-4=256-4$

⇒ $2x = 252$

⇒ $x =\frac{252}{2}$

⇒ $x = 126$

$x = 126$ is the solution for equation $\sqrt{2x+4}=16$.
