Question

$$4+\sqrt{z+9}=5$$

Solve for z

$z=-8$

Steps for Solving Radical Equations

Subtract $4$ from both sides of the equation.

$$\sqrt{z+9}+4-4=5-4$$

Subtracting $4$ from itself leaves $0$.

$$\sqrt{z+9}=5-4$$

Subtract $4$ from $5$.

$$\sqrt{z+9}=1$$

Square both sides of the equation.

$$z+9=1$$

Subtract $9$ from both sides of the equation.

$$z+9-9=1-9$$

Subtracting $9$ from itself leaves $0$.

$$z=1-9$$

Subtract $9$ from $1$.

$$z=-8$$
