what if for one equation it's 3=5, and for another it's also 3=5?
*April 1, 2009*

**math**

oh,ok.. let's say for one equation you get 2=2, and for another, you get 4=4.is the ordered pair a solution of both equations?
*April 1, 2009*

**math**

what does it mean for an ordered pair to be a soltuin of both equations? for example,for this system, is the ordered pair a solution of both equations? (2,2.4) 4x+5y=20 2x+6y=10
