answer
attempt 1 out of 2
x =

Explanation:

Step1: Remove the parentheses

$$\begin{align*} -x&=3-(3x + 5)\\ -x&=3-3x-5 \end{align*}$$

Step2: Simplify the right - hand side

$$ -x=-3x - 2 $$

Step3: Add \(3x\) to both sides

$$\begin{align*} -x+3x&=-3x - 2+3x\\ 2x&=-2 \end{align*}$$

Step4: Divide both sides by 2

$$ x=\frac{-2}{2}=-1 $$

Answer:

\(x = - 1\)
