Hello!
The first step is to remove the parenthesis of the equation. To do it, we have to multiply the value inside of it by 4, look:
[tex]\begin{gathered} -2=4(3x-2)-6 \\ -2=12x-8-6 \end{gathered}[/tex]Now, let's group the similar terms:
[tex]\begin{gathered} -2=12x-8-6 \\ -2=12x-14 \\ -2+14=12x \\ 12=12x \\ \\ x=\frac{12}{12} \\ \\ \boxed{x=1} \end{gathered}[/tex]Note:
As I wrote -14 in the other side of the equation, the signal has changed to +.
x = 1.
