Solve Graphically $16 \Omega$ Their Difference Is $2 \Omega$ Find the Two Resistances

Multiple Choice

Solve graphically. The sum of two resistances is $16 \Omega$ . Their difference is $2 \Omega$ . Find the two resistances. If we let $R _ { 1 }$ and $R _ { 2 }$ be the two resistances, the equations are $\begin{array} { l } R _ { 1 } + R _ { 2 } = 16 \\R _ { 1 } - R _ { 2 } = 2\end{array}$
