Enter the simultaneous equations you wish to solve by entering the two lines in standard form:

x + y =

x + y =

 

They cross at (x,y) = ( ,)


Try this: put in any 3 consecutive numbers in the equations. Like

3x + 4y = 5 and 9x + 10y = 11

Where do they cross? Try more, even negative numbers!

Why does this work?
