## ExoticInspirit one year ago 4x-12/6x how do i solve

1. Mertsj

That is not an equation. Equations have equal signs.

2. exoticinspirit

rational expression?

3. exoticinspirit

either way i need help

4. anonymous

which of these is your problem? |dw:1437444806204:dw|

5. exoticinspirit

the one on top

6. anonymous

are you trying to reduce it?

7. anonymous

what is the problem asking you to do?

8. exoticinspirit

simplify

9. anonymous

you can't do anything with the x's because the 12 doesn't have an x. You can cancel out the gcf of the numbers 4,12, and 6

10. exoticinspirit

this|dw:1437445105522:dw|

11. exoticinspirit

i did this so far im not sure

12. anonymous

that's right. then the 2's cancel

13. exoticinspirit

oh do i need to divide the 2 and 3 after i cancel out the other twos

14. anonymous

no I'd leave it as$\frac{ 2x-6 }{ 3x }$

15. exoticinspirit

cant i simplify it more?

16. anonymous

You can split the fraction, but I don't know if that's actually simpler

17. anonymous

|dw:1437445320003:dw|

18. anonymous

then reduce each of those

19. exoticinspirit

|dw:1437445369327:dw|

20. exoticinspirit

than i can cross out the twos? and it would equal 3x

21. anonymous

no you can't do that. you have to reduce each fraction individually|dw:1437445441349:dw|

22. exoticinspirit

oh i see but cant i simplify it even more? like subtract 2-2 and 3-x

23. exoticinspirit

and if i cant do you know the reason why

24. anonymous

no. remember to subtract fractions you need a common denominator. 3x was the common denominator before we split the fractions

25. exoticinspirit

but if i was multiplying would it work if i did 2(2) and 3(x)

26. anonymous

yes that works for multiplication.

27. exoticinspirit

oh okay thank you so very much

28. anonymous

you're welcome
