Solve (4)y^2-z=0

$$( 4 ) y ^ { 2 } - z = 0$$

Solve for z

$$z=4y^{2}$$

Steps for Solving Linear Equation

Subtract 4y^{2} from both sides. Anything subtracted from zero gives its negation.

$$-z=-4y^{2}$$

Divide both sides by -1.

$$\frac{-z}{-1}=-\frac{4y^{2}}{-1}$$

Dividing by -1 undoes the multiplication by -1.

$$z=-\frac{4y^{2}}{-1}$$

Divide -4y^{2} by -1.

$$z=4y^{2}$$

Solve for y

$$y=\frac{\sqrt{z}}{2}$$

$$y=-\frac{\sqrt{z}}{2}\text{, }z\geq 0$$
