like terms are the positive terms , first collect them

3. Faman39

I dont get the whole process way they showed

4. Faman39

i m confuse from step 3

5. singhmmm

solve like this (2x/5 +x/5) +4/5-1 =3x/5+4/5-1 =(3x+4)/5-1 =(3x+4-5)/5

6. JA1

i was gonna answer but it seems singhmmm has this under control

7. singhmmm

then u will get (3x-1)/5

8. Faman39

Thank you so much guys coming for help and thanks alot @singhmmm :)

9. singhmmm

ur welcum

10. Faman39

what abt 4/5?

11. Faman39

I need better explanation, how do we come up there, i tried to understand, it seems still blurry to me

12. JA1

what do you need?

13. singhmmm

solve like this (2x/5 +x/5) +4/5-1 =3x/5+4/5-1 here we will take the LCM of 3x/5+4/5 =(3x+4)/5-1 =(3x+4-5)/5 =(3x-1)/5

14. JA1

O_O um ok just a sec

15. Faman39

but it showed 3/5 x - 1/5

16. Faman39

@Chlorophyll i m kinda confused with this

17. Chlorophyll

Rearrange to combine x terms together ( commutative ) 2x/ 5 + x/5 = 3x/ 5 then, the rest is constant: -1 + 4/5 = -5/5 + 4/5

18. Chlorophyll

@Faman39 Pretend x terms are candies, constant numbers are cookies you want to sort them out, so it'll be easier to combine together!

19. Faman39

3x/5 i understand this but last one, it is still making me confuse

20. Faman39

i meant last part - 1/5

21. Chlorophyll

Do you know that in order to combine -1 + 4/5, you need to convert into same denominator?

22. Faman39

i thought -1 +4/5 would be like that 3/5

23. Chlorophyll

No, -1 = - 5/5

24. Faman39

oh ok, thank you so so much for helping @Chlorophyll, i been so confused with this little thing, thank you so much

25. Chlorophyll

Because: 1 = 5/5 --> -1 = -5/5

26. Faman39

ok, it was kinda tricky, i m pretty clear now with your help, thank you! :)

27. Chlorophyll

As long as the numerator is the same as denom. , the result is 1
