Question

How do you find `x` in the equation `-2 - 6x = 19`?

Answer 1

`x=-7/2`

Explanation:

`-2-6x=19`

Add `2` on each side of the equation to get rid of the `-2` on the left-hand side (whatever you do to one side of the equation, you must do to the other side)

`-2+2-6x=19+2`

`0-6x=19+2`

`-6x=21`

To solve for `x`, we must get `x` by itself. So, divide both sides of the equation by `-6`

`(-6x)/-6=21/-6`

`x=-21/6`

Simplify as much as possible, in this case, `3` is common in the denominator and numerator

`x=-7/2`
