Solve {l}{x=5}{y=4}{z=x*sqrt{y}*x}{text{Solvefor}atext{where}}{a=z}

$$\left. \begin{array} { l } { x = 5 }\\ { y = 4 }\\ { z = x \cdot \sqrt{y} \cdot x }\\ { \text{Solve for } a \text{ where} } \\ { a = z } \end{array} \right.$$

Solve for x, y, z, a

$$a=50$$

Solution Steps

Consider the third equation. Insert the known values of variables into the equation.

$$z=5\sqrt{4}\times 5$$

Calculate the square root of 4 and get 2.

$$z=5\times 2\times 5$$

Multiply 5 and 2 to get 10.

$$z=10\times 5$$

Multiply 10 and 5 to get 50.

$$z=50$$

Consider the fourth equation. Insert the known values of variables into the equation.

$$a=50$$

The system is now solved.

$$x=5 y=4 z=50 a=50$$
