What multiple of equation should be subtracted from equation ?
After this elimination step, solve the triangular system.
If the right-hand side changes to , what is the new solution?
Step-1:Finding the triangular system after elimination:
Finding the multiple of equation should be subtracted from equation :
Given,
We know that ,
The system of the linear equation be .
writing the given equation as system of the linear equation
So,
Hence, two is the the multiple of equation should be subtracted from equation .
Step-2: Finding the new solution, the right-hand side changes to :
The new system of the linear equation
Hence the equation be
Solve the above equations we get,
Substitute in in
Hence, the new solutions are .
