Question

How do you solve `-12= \frac { x } { 18}`?

Answer 1

See a solution process below:

Explanation:

Multiply each side of the equation by `color(red)(18)` to solve for `x` while keeping the equation balanced:

`color(red)(18) xx -12 = color(red)(18) xx x/18`

`-216 = cancel(color(red)(18)) xx x/color(red)(cancel(color(black)(18)))`

`-216 = x`

`x = -216`
