Solve {l}{170*70*22=y}{y-40000=x}{z=x}{text{Solvefor}atext{where}}{a=z}

$$\left. \begin{array} { l } { 170 \cdot 70 \cdot 22 = y }\\ { y - 40000 = x }\\ { z = x }\\ { \text{Solve for } a \text{ where} } \\ { a = z } \end{array} \right.$$

Solve for y, x, z, a

$$a=221800$$

Solution Steps

Consider the first equation. Multiply 170 and 70 to get 11900.

$$11900\times 22=y$$

Multiply 11900 and 22 to get 261800.

$$261800=y$$

Swap sides so that all variable terms are on the left hand side.

$$y=261800$$

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

$$261800-40000=x$$

Subtract 40000 from 261800 to get 221800.

$$221800=x$$

Swap sides so that all variable terms are on the left hand side.

$$x=221800$$

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

$$z=221800$$

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

$$a=221800$$

The system is now solved.

$$y=261800 x=221800 z=221800 a=221800$$
