Thread: Make x the subject

I thought I was getting the hang of Algebra but this question has had me stumped all day.

Y=(XY+2)/(3X-4)

make X the subject.

Apparently the answer is X=(2Y+1)/Y

I can't get anywhere near the answer. Any help would be appreciated.

Multiply through by (3X-4)


Distribute Y on the left:

Spoiler:

Bring X on one side



Factor 2 on the right



2 will cancel and divide by Y

Thankyou.

After all that it was really quite simple.

Practice, practice, practice. I think that is what I need.
