7/4 hwork solve

Question

Solve the equation using factoring or the quadratic formula, whichever is appropriate.

(1/y+3)-(1/y)=1/9

Answer 1

(1/y+3)-(1/y)=1/9 

 

Do you mean 1/(y+3)-1/y = 1/9  ?  [I'M THINKING THIS IS RIGHT...YOU FAILED TO PARENTHESIZE A TWO-TERM DENOMINATOR]

 

Multiply by the LCD 9(y+3)(y) in order to CLEAR FRACTIONS.

 

You then get 9y - (9y+3) = (y+3)(y) and this should put you into familiar territory.

Distribute, collect like terms, etc...and you will have a quadratic equation, which you can solve.
