Solve by the elimination method. Is there a solution?

2r-5s= -11
5r+2s= 16

  • Elimination method -

    Try to get rid of the r first. Multiply the top row by -5 and the bottom row by 2. solve for s.

    Get rid of the s next, multiplying the top by 2 and the bottom by 5. solve for r.

    There should be a solution.

  • Elimination method -

    3r-4s=3
    4r+3s=39
