 Question 199246: 4) Solve. (n over n-4/9) -(n over n+4/9)= (1 over n) Pretty please will someone help me solve this? :)Answer by jim_thompson5910(28476)   (Show Source): You can put this solution on YOUR website! Start with the given equation. Factor out (to make the inside terms have whole numbers) Multiply both the numerator and denominator by the reciprocal of Multiply every term on both sides by the LCD . Doing this will eliminate all of the fractions. Simplify Rearrange the terms. Multiply Distribute Combine like terms. FOIL Subtract from both sides. Combine like terms. Divide both sides by -9. Reduce Take the square root of both sides. or Break up the "plus/minus" or Take the square root of to get So the solutions are or
