    what do you mean by simultaneous equations?

  • Math - , Tuesday, April 14, 2009 at 5:56pm

    The type of promblem you are dealing with is a set (in this case 2) simultaneous equations. You use the two equations TOGETHER to solve for x and y. Now do you get it?

    but how do you set it up as simultaneous equations?
