Question

How do you solve `9- 2c + c= - 13`?

Answer 1

See the entire solution process below:

Explanation:

First, combine like terms on the left side of the equation:

`9 + (-2 + 1)c = -13`

`9 + (-1)c = -13`

`9 - c = -13`

Next, subtract `color(red)(9)` from each side of the equation to isolate the `c` term while keeping the equation balanced:

`-color(red)(9) + 9 - c = -color(red)(9) - 13`

`0 - c = -22`

`-c = -22`

Now, multiply each side of the equation by `color(red)(-1)` to solve for `c` while keeping the equation balanced:

`color(red)(-1) xx -c = color(red)(-1) xx -22`

`c = 22`
