Step-by-step explanation:
Supposing that we have the lines
x+2=10y
and
3x+6=Yc.
Note that dividing by 3 the second line can be rewritten as
x + 2= Y c/3.  
Remember that a line is written as  , in our case, both lines have
, in our case, both lines have  and
 and  . Therefore, in orther that the two lines are equal, we need that
. Therefore, in orther that the two lines are equal, we need that  , hence
, hence
