Numpy: Is there any simple way to solve equation in form Ax = b such that some x's takes fixed values
So basically I want to solve Ax = b but I want the value of x1 to always be equation to say 4.
For example, if A is 3x3 and x is 3x1 then the answer of the above equation should be in form x = [4, x2, x3]
