How to do?
matrix multiplication
Technically, you just need to write the linear equation into coeffient matrix. The answer is :
T =
[1 -1 0 0]
[0 0 1 0]
[1 2 0 -1]
[0 0 0 1]
>>9167274
that doesn't make sense? I cant find T with matrix multiplication
>>9167277
multiply t (with blanks for entries) by the x vector and solve for the blanks
