Question

-3x-6=9x+6 let's if we on the same page

Answer 1

Answer:

The solution to the equation is;

$x=-1$

Explanation:

Given the equation;

$-3x-6=9x+6$

firstly, let us subtract 6 from both sides;

$\begin{gathered} -3x-6-6=9x+6-6 \\ -3x-12=9x \end{gathered}$

then we can add 3x to both sides;

$\begin{gathered} -3x+3x-12=9x+3x \\ -12=12x \end{gathered}$

lastly, divide both sides by 12;

$\begin{gathered} \frac{-12}{12}=\frac{12x}{12} \\ -1=x \\ x=-1 \end{gathered}$

Therefore, the solution to the equation is;

$x=-1$
