Question

How do you solve: `4 = -8 + 3x`?

Answer 1

See the entire solution process below:

Explanation:

First, add `color(red)(8)` to each side of the equation to isolate the `x` term while keeping the equation balanced:

`color(red)(8) + 4 = color(red)(8) + (-8) + 3x`

`12 = 0 + 3x`

`12 = 3x`

Now, divide each side of the equation by `color(red)(3)` to solve for `x` while keeping the equation balanced:

`12/color(red)(3) = (3x)/color(red)(3)`

`4 = (color(red)(cancel(color(black)(3)))x)/cancel(color(red)(3))`

`4 = x`

`x = 4`
