Thread: rewrite equation

ok i have this y = 1 / (x - 1)

answer is

x = 1 / y + 1 / 1

can someone explain in steps?

There are many ways to solve for x in something like this. (writing 1/1 is unnecessary AND unaesthetic)

One method:

..................multiply both sides by

..........now divide both sides by

..............now add 1 to both sides

lol yes i know im sorry it wasnt 1 / 1 its x = (1/(y) + 1) / 1

that makes no difference, and is perhaps even more unaesthetic

anything divided by 1 is itself, so having the whole right side over 1 is useless

..........now divide both sides by
ok guess at this point i dont understan why u dont distribute the y to(x-1)?

that would be mixing x and y wouldn't it? our objective is to solve for x, thus we want to get x by itself on one side. distributing the y does not accomplish that

thanks for that and sorry about that extra post
