You should notice that in post#1 you have written

y=2/3=5/12

and in post #3 you have

Y-2/3=5/12

these are not the same, that is why I asked.

This one is in a form we can solve for

Add 2 / 3 to both sides.

Do you follow this so far? Are you familiar with how to add to fractions? Or do you need some help with that?

]]>This is not in the right form.

y=2/3=5/12

For the next one:

Subtract 1 / 9 from both sides.

For the last

2/3x=7=ty

which variable do you want to solve for?
