Solve {l}{x+3=5}{y=2*2}{z=y}{a=z}{text{Solvefor}btext{where}}{b=a}

$$\left. \begin{array} { l } { x + 3 = 5 }\\ { y = 2 \cdot 2 }\\ { z = y }\\ { a = z }\\ { \text{Solve for } b \text{ where} } \\ { b = a } \end{array} \right.$$

Solve for x, y, z, a, b

$$b=4$$

Solution Steps

Consider the first equation. Subtract 3 from both sides.

$$x=5-3$$

Subtract 3 from 5 to get 2.

$$x=2$$

Consider the second equation. Multiply 2 and 2 to get 4.

$$y=4$$

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

$$z=4$$

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

$$a=4$$

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

$$b=4$$

The system is now solved.

$$x=2 y=4 z=4 a=4 b=4$$
