Question

How do you solve `5+9x=2012`?

Answer 1

See the entire solution process below:

Explanation:

Step 1) Subtract `color(red)(5)` from each side of the equation to isolate the `x` term while keeping the equation balanced:

`5 + 9x - color(red)(5) = 2012 - color(red)(5)`

`5 - color(red)(5) + 9x = 2007`

`0 + 9x = 2007`

`9x = 2007`

Step 2) Divide each side of the equation by `color(red)(9)` to solve for `x` while keeping the equation balanced:

`(9x)/color(red)(9) = 2007/color(red)(9)`

`(color(red)(cancel(color(black)(9)))x)/cancel(color(red)(9)) = 223`

`x = 223`
