# Thread: Help appreciated! :D solving ( 3y / 7 ) + ( y / 14) < -1

1. ## Help appreciated! :D solving ( 3y / 7 ) + ( y / 14) < -1

I don't remember how to do this....

(3y/7)+(y/ 14)<−1

So, here is my work...

(3y/7)+(y/ 14) < -1

[2] (3y/7)+(y/ 14) < -1

(6y/14)+(y/ 14) < -1

7y / 14 < -1

1/2y < -1

y < -2

Is this correct?

Thanks!!! :) :D

(6y/14)+(y/ 14) < -1

7y / 14 < -1

1/2y < -1

y < -2

Is this correct?

Thanks!!!

Issac Asimov once said something to the affect of "Although it is sometimes a convenience, I don't have to remember things, A genius can work them out and, since I can work them out, I'm a genius."

[2] (3y/7)+(y/ 14) < -1 <------ this line

(6y/14)+(y/ 14) < -1

7y / 14 < -1

1/2y < -1

No, it's not correct.

The line above makes it incorrect.

[2](3y/7) = 6y/7, not 6y/14.

- - - - - -- - - -- - - - - - -- - - - - - - -

Look at:

(3y/7) + (y/14) < -1

[2/2](3y/7) + (y/14) < -1

(6y/14) + (y/14) < -1

7y/14 < -1

(1/2)y < -1

y < -2
