Question

$$\sqrt { x - 7 } = 21$$

Solve for x

$x=448$

Steps for Solving Radical Equations

Square both sides of the equation.

$$x-7=441$$

Add $7$ to both sides of the equation.

$$x-7-\left(-7\right)=441-\left(-7\right)$$

Subtracting $-7$ from itself leaves $0$.

$$x=441-\left(-7\right)$$

Subtract $-7$ from $441$.

$$x=448$$
