$$\left. \begin{array} { l } { a = 4 }\\ { b = {({(18 + 6)} / a)} + {(a + 7)} - 16 }\\ { \text{Solve for } c \text{ where} } \\ { c = b } \end{array} \right.$$

Solve for a, b, c

$$c=1$$

Solution Steps

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

$$b=\frac{18+6}{4}+4+7-16$$

Add 18 and 6 to get 24.

$$b=\frac{24}{4}+4+7-16$$

Divide 24 by 4 to get 6.

$$b=6+4+7-16$$

Add 6 and 4 to get 10.

$$b=10+7-16$$

Add 10 and 7 to get 17.

$$b=17-16$$

Subtract 16 from 17 to get 1.

$$b=1$$

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

$$c=1$$

The system is now solved.

$$a=4 b=1 c=1$$
