Question

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

Answer 1

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`
