7-121.

Which of the following statements are true? If true, explain how you know, and if not, show why not.

1. $\frac { x + 3 } { 5 } = \frac { x } { 5 } + \frac { 3 } { 5 }$

Try multiplying both sides by $5$.

1. $\frac { 5 } { x + 3 } = \frac { 5 } { x } + \frac { 5 } { 3 }$

Is there something you can multiply both sides by to eliminate the fractions?

The equation is only true when

$\textit{x}=\frac{-3\pm3\textit{i}\sqrt{3}}{2}$
