Consider the system of equations: 3x+4y=67 and 5x-y=35

Edmundo used the multiplication property of equality so that the y-terms would be eliminated when the equations were added. What was the resulting equation?

3x+4y=67    multiplication property of equality so that the y-terms would be eliminated 
5x-y=35  <-----   Multiply by 4

20x - 4y = 140
  3x+ 4y  =  67    Add

  23x = 207

Looks complete to me.  Unless you want to solve for x or y.
