Question

What value of x makes the following equation true?
15+3x=3(2−2x)

Answer 1

`\boxed {x = -1}`

Explanation:

Solve for the value of
`x`:

`15 + 3x = 3(2 - 2x)`

-Use Distributive Property:

`15 + 3x = 3(2 - 2x)`

`15 + 3x = 6 - 6x`

-Take
`6x` and add it to
`3x`:

`15 + 3x + 6x = 6 + 6x - 6x`

`15 + 9x = 6`

-Subtract both sides by
`15`:

`15 - 15 + 9x = 6 - 15`

`9x = -9`

-Divide both sides by
`9`:

`(9x)/(9) = (-9)/(9)`

`\boxed {x = -1}`

Therefore, the value of
`x` is
`-1`.
