You can put this solution on YOUR website!
There are many ways to solve a system like this, including:
  • Substitution Method
  • Linear Combination (aka Elimination) Method
  • Matrix methods, including:
    • Gaussian Elimination
    • Inverse Matrices
  • Cramer's Rule (determinants)
Since it would not be helpful for me (or any tutor) to use a method you know nothing about, I think it would be best for you to re-post your question and include either:
  • The method you would like to see; or
  • A list of methods you have learned so the tutors can pick one you can recognize.
