Solve {l}{w-9=-4.1}{x=41+9}{y=x}{z=y}{text{Solvefor}atext{where}}{a=z}

$$\left. \begin{array} { l } { w - 9 = -4.1 }\\ { x = 41 + 9 }\\ { y = x }\\ { z = y }\\ { \text{Solve for } a \text{ where} } \\ { a = z } \end{array} \right.$$

Solve for w, x, y, z, a

$$a=50$$

Solution Steps

Consider the first equation. Add 9 to both sides.

$$w=-4.1+9$$

Add -4.1 and 9 to get 4.9.

$$w=4.9$$

Consider the second equation. Add 41 and 9 to get 50.

$$x=50$$

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

$$y=50$$

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

$$z=50$$

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

$$a=50$$

The system is now solved.

$$w=4.9 x=50 y=50 z=50 a=50$$
