You can put this solution on YOUR website!
I suspect the following are reasons you have not received a response:
Solving systems like this take a considerable amount of effort
You have probably been taught quite a few ways to solve these systems, including Substitution, Linear Combination (aka Elimination), Gaussian elimination, Inverse Matrices and Cramer's Rule (detreminants)
Often these problems tell you which method to use but you do not mention this.
Tutors are less likely to invest the effort to solve a large problem without knowing which method you are supposed to use.
Please re-post and include a preferred method, a list of preferred methods, or a "using any method" statement so tutors will know if/how we can help you.
