The elimination method puts two equations on top of each other and "adds" or "subtracts" one equation from another to eliminate a variable. Say we want to get rid of y. You would manipulate the equations so that the yvalues in each would be opposite integers. So here, we can manipulate 3y to 9y so the y's will be cancelled with the 9y in the second equation.

5x3y=16 times three> 15x9y=48 second equation > x+9y= 64 adding both equations > 16x+0y= 16 so, 16x=16 and x=1

Now you can solve for y by substituting 1 into x, and you'll have your ordered pair
