3%2Fr%2B4-1%2Fr=1%2Fr Start with the given equation


Multiply every term by the LCD r to clear the fractions.


3%2B4r-1=1 Multiply and simplify.


4r%2B2=1 Combine like terms on the left side.


4r=1-2 Subtract 2 from both sides.


4r=-1 Combine like terms on the right side.


r=%28-1%29%2F%284%29 Divide both sides by 4 to isolate r.

Answer:

So the answer is r=-1%2F4


Which approximates to r=-0.25
