$$\left. \begin{array} { l } { A + 3 ^ {2} = 8 }\\ { a = 3 ^ {2} }\\ { b = A }\\ { \text{Solve for } c,d \text{ where} } \\ { c = a }\\ { d = b } \end{array} \right.$$

Solve for A, a, b, c, d

$$c=9$$

$$d=-1$$

Solution Steps

Consider the first equation. Calculate 3 to the power of 2 and get 9.

$$A+9=8$$

Subtract 9 from both sides.

$$A=8-9$$

Subtract 9 from 8 to get -1.

$$A=-1$$

Consider the second equation. Calculate 3 to the power of 2 and get 9.

$$a=9$$

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

$$b=-1$$

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

$$c=9$$

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

$$d=-1$$

The system is now solved.

$$A=-1 a=9 b=-1 c=9 d=-1$$
