Solve {l}{A=1}{B=2}{C=2^2-B^2/2}

$$\left. \begin{array} { l } { A = 1 } \\ { B = 2 } \\ { C = \frac { 2 ^ { 2 } - B ^ { 2 } } { 2 } } \end{array} \right.$$

Solve for A, B, C

$$A=1$$

$$B=2$$

$$C=0$$

Solution Steps

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

$$C=\frac{2^{2}-2^{2}}{2}$$

Calculate 2 to the power of 2 and get 4.

$$C=\frac{4-2^{2}}{2}$$

Calculate 2 to the power of 2 and get 4.

$$C=\frac{4-4}{2}$$

Subtract 4 from 4 to get 0.

$$C=\frac{0}{2}$$

Zero divided by any non-zero number gives zero.

$$C=0$$

The system is now solved.

$$A=1 B=2 C=0$$
