Question

How do you solve `15-x/8=4`?

Answer 1

See a solution process below:

Explanation:

First, subtract `color(red)(15)` from each side of the equation to isolate the `x` term while keeping the equation balanced:

`-color(red)(15) + 15 - x/8 = -color(red)(15) + 4`

`0 - x/8 = -11`

`-x/8 = -11`

Now, multiply each side of the equation by `color(red)(-8)` to solve for `x` while keeping the equation balanced:

`color(red)(-8) xx x/-8 = color(red)(-8) xx -11`

`cancel(color(red)(-8)) xx x/color(red)(cancel(color(black)(-8))) = 88`

`x = 88`
