Given the equation $x-y = 1$, I want to rearrange it to solve for $y$. The answer in the learning materials I have is $y = x-1$.
When I try to rearrange the equation myself I go through the following thought process:
$x-y =1$ --- first I think I want to get the x over to the right hand side of the equals sign so that I'm left with the $-y$ on the left side. So I do minus $x$ on both sides:
$-y = 1-x$
---Then I'm thinking that I want to change the minus $y$ to positive $y$. So then I multiply both sides by minus $1$
$y = -1 + x$
--Then I assume I can just switch around the position of $-1$ and $x$ to give $y = x-1$
My question is: Is this the same thought process that you would go through to solve this simple equation or am I taking too many unnecessary steps?
