Solve Rational Equations with Variables in the Denominators
First, write the value(s) that make the denominator(s) zero. Then solve the equation.
- $$\frac { 5 } { x + 1 } + \frac { 2 } { x - 1 } = \frac { 4 } { ( x + 1 ) ( x - 1 ) }$$

A) $x \neq - 1,1$ ; $\varnothing$
B) $x \neq - 1,1 ; \{ 2 \}$
C) $x \neq - 1 ; \{ 1 \}$
D) No restrictions; $\{ 1 \}$
