hi Melody,
{rll...} is the alignment.
1. Field r (right-alignment) bevor first "&"
2. Field l (left-alignment) after first "&"
3. Field l (left-alignment) after second "&"
and so on...
r = right alignment
c = center alignment
l = left alignment
I hope, I could help you

$$5=11+2(x-1)\\
5-11=11+2(x-1)-11\\
-6=2x-2\\
-6+2=2x-2+2\\
-4=2x\\
-4/2=x\\
x=-2$$
5=11+2(x-1) x?
$$\begin{array}{rll}
5&=&11+2(x-1)\quad | \quad -11\\
5-11&=& 2(x-1)\\
-6&=& 2(x-1)\quad | \quad :2\\
-\frac{6}{2}&=& (x-1)\\
-3&=& x-1\quad | \quad +1\\
-3+1&=& x\\
-2&=& x\\
\end{array} \\
\boxed{x=-2}\\$$
Latex Code:
\begin{array}{rll}
5&=&11+2(x-1)\quad | \quad -11\\
5-11&=& 2(x-1)\\
-6&=& 2(x-1)\quad | \quad :2\\
-\frac{6}{2}&=& (x-1)\\
-3&=& x-1\quad | \quad +1\\
-3+1&=& x\\
-2&=& x\\
\end{array} \\
\boxed{x=-2}\\
Proof:
$$\begin{array}{rll}
5&=&11+2*(\textcolor[rgb]{1,0,0}{-2}-1)\\
5&=&11+2*(-3)\\
5&=&11-2*3\\
5&=&11-6\\
5&=&5\\
\end{array} \\$$
Latex code:
\begin{array}{rll}
5&=&11+2*(\textcolor[rgb]{1,0,0}{-2}-1)\\
5&=&11+2*(-3)\\
5&=&11-2*3\\
5&=&11-6\\
5&=&5\\

hi Heureka,
I have only done this type of setting out with equarray.
but i haven't been able to get equarray to work on this forum.
Thankyou for showing me how I can do it with array.
I don't quite understand what {rll}stands for.
Can you explain please?
I think I will try equarray again and see if I can get it to work. I tried again - it still doesn't work.
