Solve by the elimination method. Is there a solution? 2r-5s= -11 5r+2s= 16

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.

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