New
can not add List b (Line12): have to split in 2 lines (13,14) to calculate
Worksheet ... Line 12
12: Transpose(L)*Y  b > ? 13:Transpose(L)*Y >{(4 * y1)  (2 * y2)  (5 * y3), (6 * y2) + (2 * y3), (4 * y3)} 14: $13  b >{(4 * y1)  (2 * y2)  (5 * y3)  3, (6 * y2) + (2 * y3)  5, (4 * y3) + 7}

I can reduce the problem by using Transpose
using function Transpose in a matrix/list product you can not add a vector
b = {15, 79, 189}
L = {{3, 0, 0}, {5, 4, 0}, {1, 7, 1}}
OK: (Transpose(L) * {x1,x2,x3})
??: (Transpose(L) * {x1,x2,x3})  b
I think there is a problem with the format shown for (Transpose(L) * {x1,x2,x3})
it is shown like a simple list not matrix but it must be a matrix
you can try flatten((Transpose(L) * {x1,x2,x3}))b
