Question

How do you solve the two step equation `12-3x=6`?

Answer 1

See a solution process below:

Explanation:

Step 1) Subtract `color(red)(12)` from each side of the equation to isolate the `x` term while keeping the equation balanced:

`12 - color(red)(12) - 3x = 6 - color(red)(12)`

`0 - 3x = -6`

`-3x = -6`

Step 2) Divide each side of the equation by `color(red)(-3)` to solve for `x` while keeping the equation balanced:

`(-3x)/color(red)(-3) = (-6)/color(red)(-3)`

`(color(red)(cancel(color(black)(-3)))x)/cancel(color(red)(-3)) = 2`

`x = 2`
