oops I forgot to put have many solutions

directrix · Answer

*How* many solutions?

anonymous · Answer

It just says Show that the equations 8a-10b=1/3 and 
20a-25b=5/6 have many solutions

directrix · Answer

These two equations are the same line.

(8a - 10b = 1/3) -- multiply by 5/2 --> 20a -25b = 5/6

which is identical to the second equation.

 (20a - 25b = 5/6)

In a sense, the two lines are one and intersect each other in every one of the infinitely many points on the line. That would be infinitely many solutions.
