Solve {l}{A=3}{a=A*4}{b=a}{c=b}{text{Solvefor}dtext{where}}{d=c}

$$\left. \begin{array} { l } { A = 3 }\\ { a = A \cdot 4 }\\ { b = a }\\ { c = b }\\ { \text{Solve for } d \text{ where} } \\ { d = c } \end{array} \right.$$

Solve for A, a, b, c, d

$$d=12$$

Solution Steps

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

$$a=3\times 4$$

Multiply 3 and 4 to get 12.

$$a=12$$

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

$$b=12$$

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

$$c=12$$

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

$$d=12$$

The system is now solved.

$$A=3 a=12 b=12 c=12 d=12$$
