Pleasee help me a.s.a.p.

In a system of linear equations, you can pick a row multiply it with an arbitrary scalar and add it to any other row without changing the solution of the system. For example the system of linear equations 3x+3y=2.5x+3y=8 has the same solution as the x+y=2/3. 2x=8 since the first equation can be obtained by dividing 3x+3y=2 by 3 and the second equation can be obtained by multiplying 3x+3y=2 by-1 and then adding it to 5x+3y-8. Write a function lineadder(ja) that takes two integer inputs i and and a matrix (list of lists) of float variables that representa system of linear equations. The function should modily the input matrix by multiplying rowi of the input with a proper scalon and then adding it to row such that the ith element in row will be equal to zero; Answer: penalty regime:0 %)
