like terms are the positive terms , first collect them

I dont get the whole process way they showed

i m confuse from step 3

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

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

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

ur welcum

what abt 4/5?

what do you need?

O_O um ok just a sec

but it showed 3/5 x - 1/5

@Chlorophyll i m kinda confused with this

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

i meant last part - 1/5

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

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

No, -1 = - 5/5

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

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

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