Still need help?

2. anonymous

yeah

3. KendrickLamar2014

Ok lets see....

4. candyme

$\frac{ 3y-2 }{ 4 }-\frac{ 2y-1 }{ 8 }$ So you just want to combine these, correct?

5. anonymous

yup

6. KendrickLamar2014

Step 1. Distribute = $\frac{ 3 }{ 4 } y + \frac{ -1 }{ 2 } + \frac{ 1 }{ 4 } y + \frac{ -1 }{ 8 }$

7. KendrickLamar2014

Step 2. Combine Like Terms: = $( \frac{ 3 }{ 4 }y + \frac{ 1 }{ 4 } y) + (\frac{ -1 }{ 2 } + \frac{ -1 }{ 8 })$

8. candyme

I will let @KendrickLamar2014 finish, then show you a way that may/may not make sense to you

9. anonymous

ok @candyme

10. KendrickLamar2014

Which equals: $y + \frac{ -5 }{ 8 }$ and thats your answer

11. anonymous

@KendrickLamar2014 the answer key shows that it equals |dw:1444177170611:dw| 8y-5 _____ 8

12. candyme

So your book is doing it the way I did.$2(\frac{ 3y-2 }{ 4 })+\frac{ 2y-1 }{ 8 }$ Distribute that 2$\frac{ 6y-4 }{ 8 } +\frac{ 2y-1 }{ 8 }$ $\frac{ 6y+2y-4-1 }{ 8 }$$\frac{ 8y-5 }{ 8 }$

13. candyme

@KendrickLamar2014 took it a step further and simplified the 8y/8 part

14. candyme

I multiplied it by 2 in the beginning so I could place all of it on one fraction. I needed a common denominator
