Question

-5x - 4 = 3x + 12 what is the value of x

Answer 1

`\boxed {x = -2}`

Explanation:

Solve for the value of
`x`:

`-5x - 4 = 3x + 12`

-Take
`3x` and subtract it from
`-5x`:

`-5x - 4 - 3x = 3x - 3x + 12`

`-8x - 4 = 12`

-Add
`4` to both sides:

`-8x - 4 + 4 = 12 + 4`

`-8x = 16`

-Divide both sides by
`-8`:

`(-8x)/(-8) = (16)/(-8)`

`\boxed {x = -2}`

Therefore, the value of
`x` is
`-2`.
