# How do you solve for y in  y - 9 = x?

Mar 20, 2018

When we solve for setting, it means we change the equation to be something $=$ everything else

In this case, we want it to say $y =$ everything else

So we have $y - 9 = x$

Let's add $9$ to both sides

$y \cancel{- 9 + 9} = x + 9$

$y = x + 9$
