Question

How do you solve `-4+ \frac { n } { 2} = - 2`?

Answer 1

See a solution process below:

Explanation:

This is a standard 2-Step problem.

Step 1) Isolate the variable" Add `color(red)(4)` to each side of the equation to isolate the `n` term while keeping the equation balanced:

`color(red)(4) - 4 + n/2 = color(red)(4) - 2`

`0 + n/2 = 2`

`n/2 = 2`

Step 2) Multiply or Divide by the appropriate number to solve for the Variable: Multiply each side of the equation by `color(red)(2)` to solve for `n` while keeping the equation balanced:

`color(red)(2) xx n/2 = color(red)(2) xx 2`

`cancel(color(red)(2)) xx n/color(red)(cancel(color(black)(2))) = 4`

`n = 4`
