Question

I am completely lost...
4b - 1/7 = 5/7
How do I solve this?

anonymous · Answer

4b= 5/7+1/7
b= (5/7+1/7)/4

anonymous · Answer

._. but I dunno how to get b isolated.

anonymous · Answer

I have just isolated be for you

anonymous · Answer

Can you tell me how? lol I suck with fractions.

anonymous · Answer

you will need to move the like terms to the same side of the equation.in this case the fractions to one side. moving the negative acroos the equal sign will make it positve

anonymous · Answer

Like terms being 1/7 and 5/7?

anonymous · Answer

yes

anonymous · Answer

so moving the -1/7 across makes it positive so you add 1/7 to the other fraction

anonymous · Answer

and to isolate b since b is multiplying 4 you will move the to the other side of the equation. It will go to divide the sum of the fraction on the right!

anonymous · Answer

i meant move the 4 to the other side

anonymous · Answer

OH so 6/7 divided by 4?

anonymous · Answer

I completely forget if one is too add denominatiors.

anonymous · Answer

Anyway, I get it more now, thank you :)

anonymous · Answer

If the denominators are the same, you add the numerators

anonymous · Answer

Ah okay.

anonymous · Answer

I get it now with this format, tyvm :D 
I understand what you mean with b = (5/7 + 1/7)/4
