Let us solve the equation to arrange the steps

In the first step, we must multiply the bracket by -3 (distributive property)

$(-3)(4)_{}+(-3)(3x)=-12-9x$

Then the equation is

Now add the like terms on the left side

$\begin{gathered} -12+(-9x+5x)=-16 \\ -12x+(-4x)=-16 \\ -12-4x=-16 \end{gathered}$

Next step, add 12 to both sides
